I believe many of the regulars would *love* to have a locked, sticky post with the subject "FAQ -- PLEASE DO NOT POST BEFORE READING" at the top of several of the individual forums that includes (and/or points to a post that contains):
-- Once and for all, explicit instructions on how to post a legible grid including the use of the CODE command. (Such as the one they have here.).
-- Instructions on how to search the forum. The built in search command is often useless. Google's Advanced Search is substantially more effective.
-- Pointers to all the popular tutorials -- Simple Sudoku, Sadman Sudoku, Susser, etc. (as well as popular helper software if deemed appropriate).
-- A pointer to basic terms used here.
-- A pointer to Gaby Vanhegan's must-have dictionary of Sudoku Dictionary/Lexicon.
-- Short answers and/or pointers to previous discussions answering frequently asked questions such as -- "Is guessing required?" "Is trial and error required?" "Are multiple solutions possible?" "How many this, that or the other are possible?" "Is it possible to include diagonals?", etc.
-- Notice to please not post solutions unless asked.
Whadda think? I'm sure there are several of us who would volunteer to put together an appropriate FAQ for you to review and post.
[EDIT:] That first paragraph should also have said that newcomers and novices would *also* greatly appreciate a FAQ, probably more so than the regulars. I know from first hand experience -- anecdotal as it may be -- that it was confusing at first. Though I was a relative Sudoku expert, having solved them for decades, still I was afraid to post for fear of repeating the same questions, I couldn't get my diagrams to look right, couldn't figure out how to include URLs, especialy to specific pages within the forum, didn't notice the basic terms page, etc. It does seem that sometimes a newcomer *never* gets her/his question answered because no one is ever able to correctly parse the question or decrypt their diagram. I come from from the olden world of the usenet, where any reasonably busy group had a FAQ. This one is *very* busy. There's no good reason not to have a FAQ.
