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.
If you think that Usain Bolt is fast think again. He reached a top speed of 42 km/hr during his 100 m run of 9.69 seconds at last years Olympics. Fossilized footprints of 6 Australian aboriginales chasing prey 20,000 years ago show that one of the men dubbed T8 reached speeds of 37 km/hr on a soft, muddy lake edge. The scientist studying this claims that with modern training, spiked shoes, and rubberized tracks these hunters 20,000 years ago would likely have reached speeds of 45 km/hr.
High jump photographs taken by a German anthropologist indicate that Tutsi men in Rwanda had to jump at least their own height for initiation ceremonies exceeding the current world record of 2.45 meters.
Neanderthal women had 10% more muscle bulk than modern European man. Trained today, these women would have 90% of the bulk of Arnold Schwarzenegger at his peak in the 1970s. Because the women have shorter arms, they would have easily defeated Arnold in an arm wrestle.
Roman legions completed at least 1.5 marathons per day carrying half their body weight in equipment.
Athens rowers (30,000) could for the most part exceed todays records.
Australian aboriginals threw hardwood spears 110 meters or more, compared to current world javelin record of 98.48 meters.

High jump photographs taken by a German anthropologist indicate that Tutsi men in Rwanda had to jump at least their own height for initiation ceremonies exceeding the current world record of 2.45 meters.
There were Tutsi men over 2.45 metres tall? Now that would be impressive.
I should clarify. The German anthropologist photographs showed the young Tutsi men jumping 2.52 meters. They had to jump at least their own height for an initiation rite to manhood, I do not know how tall they were.
Life expectancy was not mentioned, but I know that it was very low, likely 30 years at the most. Life was savage back then, and medicine was not developed too well.
Also, back then to kill one man you had to stab, strangle, knife or spear or throw them off a cliff. Modern man just presses a button and hundreds of thousands can die. Have we really advanced; do we really kick butt!
I wonder if a man's speed can be accurately measured from his fossillised footprints. Is 37km/hr perhaps the upper end of an estimated range? Maybe the guy was doing 30. And how do you extrapolate from 37 to 45 in this case?
From the spacing of the footprints, and the depth of the imprint, and having a reasonable estimate of the man's height and body structure (length of legs, etc) it is not that difficult for one versed in the biomechanics of the human body to make an accurate estimate of speed. In this case 37 km/hr is the middle of the estimated range and I think the error bars are quite small on this.
Comparing world record speeds from modern day with those going back 100 years or more one can estimate the improvement from new training methods, better shoes, etc. so it is reasonable to think that the 37 could be increased by 20% or so.
All that there is to go on is the spacing of the footprints, their size and their depth - you need to use the footprints to get your estimate of the man's physique. There is no way to accurately tell how compressible the ground was so how could it be accurately known how hard the man's feet hit? Were his feet larger or smaller than normal for his size? The further apart the footprints the faster the likely speed, but was it a tall man loping along or a shorter man going flat out? It seems to me that you could have a PHD in biomechanics and still not be able to come up with anything more than a rough estimate of speed.
