General Guidelines

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.
An interesting article about the history of various forms of correspondance chess using the latest network technology, from 1845 until the present appears on the New Scientist website today.
Such articles usually end up in an issue of the printed magazine, which may take a week or to to go on sale in NA.
Yes, the two-page article is in the April 18th printed edition of the New Scientist.
The article states that one of the reasons that chess by telegraph came a cropper was the cost, that the move "1 Kt 1 to KB3" was billed as six words. Of course there were codes developed to deal with that. "Uedemann" sticks in my brain, but that name may not represent the best coding. It is not rocket science to think up a coding that would scrunch a move, together with its board designation, into one English word. After all, two decades ago the NiCBASE and ChessBase people figured how to scrunch a move down to less than one byte (on average).
So, instead of "Board 7 stop 1 Kt 1 to KB3 stop", the transmission might be a single word, such as "contumely" or "phlogistine".

I missed that bit - I do know there was a specialized telegraph notation developed for this purpose, because I have seen it explained in old chess books. Of course just "a1a8" would encode a move in one word.
Regarding notation, how and when was the ICCF numerical system introduced?
http://en.wikipedia.org/wiki/ICCF_numeric_notation
The system was devised about 1803 by German professor J. W. D. Wildt of Gottingen. It was used 25 years later by Johann Koch, and is sometimes named after him. Ivan Savenkov supported its use in 1877 and it bears his name in Russia.

"Rutherford code, a telegraphic code devised by the English player Sir William Watson Rutherford (1853-1927) in 1880 and first used in matches between Liverpool and Calcutta. Its purpose was to enable moves in two games to be sent as a single Latin word (numbers or ciphers were not accepted by the Post Office), and is estimated to have saved more than 75 percent of the potential cost.
Having selected the moves, coding is in two stages. Working to a plan, every possible move is counted until the chosen move is reached, the position in the sequence giving a number that identifies the move. Two numbers, of one or two digits each, represent the moves of each game. The first number is multiplied by 60 and the second number added to the product, preceding zeroes being added if necessary to the total to give a four-digit number.
To convert the four digits to a word, the thousands and hundreds digits, which will be in the range 00 to 39, are represented by 40 Latin roots given in a table, the tens by 10 prefixes, and the units by 10 suffixes. Thus 2231 is broken down: 22 = rog, 3 = de, 1 = as = derogas.
Decoding is the reverse process. Rutherford believed that there would never be more than 50 legal moves in any position.
After regulations were altered to allow ciphers to be transmitted, the simpler Gringmuth Notation became the popular choice." [Oxford Companion to Chess, 2nd ed.]
I'm not sure I understand the method completely, but it must have taken a long time to code/decode a move. Uedemann Code was an earlier attempt with a fatal flaw - the transposition of two letters, a common transmission error, could result in a plausible move. Gringmuth notation avoids this possibility, and is recognized by FIDE. However, in one of those ironies of nomenclature, FIDE called it Uedemann Code anyway.
