Greetings. We added a page "Fundamental Concepts" to the wiki so that we might have a very specific reference to pass along to people with questions, and to add links to definitions throughout the wiki. http://www.haskell.org/hawiki/FundamentalConcepts A lot of concepts need to be filled in, and if you haven't participated in the Wiki yet, now is a good time :) If you've never used a wiki, you can read about it here: http://www.haskell.org/hawiki/HelpForBeginners You might model your explanations after a page I wrote for PatternMatching which has: - a reference to a tutorial - a reference to the haskell report - an explanation - some examples Feel free to extend and / or correct anything already there. The front page of the wiki is here: http://www.haskell.org/hawiki/FrontPage peace, isaac
