General Guidelines
---- Nous avons besoin d'un traduction français!
Some Basics
1. Under Board "Frequently Asked Questions" (FAQs) there are 3 sections dealing with General Forum Usage, User Profile Features, and Reading and Posting Messages. These deal with everything from Avatars to Your Notifications. Most general technical questions are covered there. Here is a link to the FAQs. https://forum.chesstalk.com/help
2. Consider using the SEARCH button if you are looking for information. You may find your question has already been answered in a previous thread.
3. If you've looked for an answer to a question, and not found one, then you should consider asking your question in a new thread. For example, there have already been questions and discussion regarding: how to do chess diagrams (FENs); crosstables that line up properly; and the numerous little “glitches” that every new site will have.
4. Read pinned or sticky threads, like this one, if they look important. This applies especially to newcomers.
5. Read the thread you're posting in before you post. There are a variety of ways to look at a thread. These are covered under “Display Modes”.
6. Thread titles: please provide some details in your thread title. This is useful for a number of reasons. It helps ChessTalk members to quickly skim the threads. It prevents duplication of threads. And so on.
7. Unnecessary thread proliferation (e.g., deliberately creating a new thread that duplicates existing discussion) is discouraged. Look to see if a thread on your topic may have already been started and, if so, consider adding your contribution to the pre-existing thread. However, starting new threads to explore side-issues that are not relevant to the original subject is strongly encouraged. A single thread on the Canadian Open, with hundreds of posts on multiple sub-topics, is no better than a dozen threads on the Open covering only a few topics. Use your good judgment when starting a new thread.
8. If and/or when sub-forums are created, please make sure to create threads in the proper place.
Debate
9. Give an opinion and back it up with a reason. Throwaway comments such as "Game X pwnz because my friend and I think so!" could be considered pointless at best, and inflammatory at worst.
10. Try to give your own opinions, not simply those copied and pasted from reviews or opinions of your friends.
Unacceptable behavior and warnings
11. In registering here at ChessTalk please note that the same or similar rules apply here as applied at the previous Boardhost message board. In particular, the following content is not permitted to appear in any messages:
* Racism
* Hatred
* Harassment
* Adult content
* Obscene material
* Nudity or pornography
* Material that infringes intellectual property or other proprietary rights of any party
* Material the posting of which is tortious or violates a contractual or fiduciary obligation you or we owe to another party
* Piracy, hacking, viruses, worms, or warez
* Spam
* Any illegal content
* unapproved Commercial banner advertisements or revenue-generating links
* Any link to or any images from a site containing any material outlined in these restrictions
* Any material deemed offensive or inappropriate by the Board staff
12. Users are welcome to challenge other points of view and opinions, but should do so respectfully. Personal attacks on others will not be tolerated. Posts and threads with unacceptable content can be closed or deleted altogether. Furthermore, a range of sanctions are possible - from a simple warning to a temporary or even a permanent banning from ChessTalk.
Helping to Moderate
13. 'Report' links (an exclamation mark inside a triangle) can be found in many places throughout the board. These links allow users to alert the board staff to anything which is offensive, objectionable or illegal. Please consider using this feature if the need arises.
Advice for free
14. You should exercise the same caution with Private Messages as you would with any public posting.
I wondered if one of our bean counters (Paul??) might help me with a statistic I'm interested in:
Of all current (so not a longitudinal stat; just a one-off snapshot of today...or whenever it may last have been done) CFC members (regardless of type), what percentage are Class B and Under?
I'm afraid I don't know of any easy way to find this out. I did google:
Canadian - Chess - Ratings - CFC Membership - Percentage Class B & Under
But the only hits were the CFC website and general sites on FIDE and rating system explanation.

You could download the tdlist.txt file and shove it into Excel and do some analysis with that...
(the tdlist.txt file is not prominently advertised on the chess.ca website - there is an unnamed reference to it
on this page: http://chess.ca/td-resources-cfc-bid-forms ...
Rating List
Tournament directors can download a complete rating list of all members both current and past. This is a delimited text file so it can be imported to any database, spreadsheet or word processor you want. The file contains CFC Numbers, Names, Expiry Dates, Ratings (both active and regular) and Rating Indicators.

Thanks.......but you are dealing with an almost techie Neanderthal. For me to do this, I'd have to say it will be a long project. I have not used Excel for at least 100 years.
I'm hoping someone may be positioned already to do this stat quickly. I am an optimist! :D
Bob
P.S. I'm hoping that I am not an anomaly in wanting to know this......since I believe at least 60% of us are below 1800 (Class B and under) - my intuitive guess - other class players may be interested?

I took a quick stab at that when I saw Bob's message. In theory it shouldn't be too hard (import it into Excel, sort by expiry date, remove the expired members, then sort by rating, etc.). Unfortunately the list isn't formatted as cleanly as it should be and it imports poorly into Excel, requiring a bit of hands-on cleanup before you can really use it. When I have a bit more time I'll take another stab at it, assuming somebody else doesn't do it first.

P.S. There is a link to it on the main CFC website under the Ratings menu.

Hi Steve,
None of that surprises me (I did not try to import it into Excel recently, but I recall having a lot of tidying up to do in the past).
I didn't see the link in the Ratings menu - thanks!
At least it can be found (and it seems like the link is more or less permanent).

Hi Steve:
Thanks for the initial try for me......as I say, I think likely this is a stat that class players might be interested in (For my purposes, I am considering B Class and Under as "class" players, though usually it includes the A Class - but I always have felt A class players were somewhat "good" players - that there is a difference between a B and A Class Player......that the B class player has not yet quite got it).
Maybe this is a stat that would be useful to the CFC? Who are its main membership?
I hope your second try will be successful, without, hopefully, requiring a wheelbarrow-load of time and effort.
Bob
P.S. Of course my position on A Class players......has nothing to do with......the fact that I hold a CFC Class A Certificate! :D

UGH! I see what you mean, Steve. The data is even more dirty than I thought. There are a LOT of errors in the file that cause Excel to mangle some rows...
Oh well, I guess it is a start and maybe it is close enough for Bob's requirements, but I have some real work to do... :)
Hi Bob. I'm off to the Canadian Senior Championship in Surrey today.
I think Roger Patterson should be able to get you what you want from the rating database he uses to support me.
I'm travelling with him and will ask. You might have to wait until Monday.
Of all current (so not a longitudinal stat; just a one-off snapshot of today...or whenever it may last have been done) CFC members (regardless of type), what percentage are Class B and Under?
Class B and under are those who have 1799 and under.
Taking stats from the file mentioned in this thread, after deleting those with 0 rating (active players), deleting "FO" and "US" members/players:
Total count: 36647
Rating 2199 starts at 470
Rating 1999 starts at 1495
Rating 1799 starts at 3526 (36647-3526)/36647 ~ 90% are under Class A (or Class B and under)
Rating 1499 starts at 9151
Rating 1199 starts at 14745
Rating 399 starts at 33940

Hi Paul:
In my life, "wait" there is not; all time stands still when retired you are! Tell Roger any forward increment of time is fine with me......they are all the same!

Membership expiry is not taken into account!!!
Hi again Egis:
That is great - exactly what I was looking for, and more, since I can now do percentile ranges for the other Classes. Thanks for taking the time. I hope others are able to also make use of this stat now.
I am shocked though.....I would never have expected that only 10% of the CFC membership is 1800 & above. We are 90% patzers???!!!
Is this the focus of the CFC...the 90%??
Or is it the case that the CFC's mission is really to focus mainly on the elite players, supported by the 90%??
I'd still like to hear Roger Patterson's comments, since he has done so much work over the years on CFC stats generally. Will he agree with Egis' result?
Bob A (Still Shocked that I was likely at one time in the top 10% of CFC members, ratings-wise)
Thanks again......I've made note of these stats as well.
I am still pretty surprised that on these criteria, still over 75% of CFC Members are "patzers".
I really did think my intuitive guess of around 60% patzers was likely close. But there are many more like me than I realized....not sure how good that is for any of us B Class & Unders.
