This has been a really good resource for me. The documentation is filling it at a decent rate and the quality is very good. Their function list has been a godsend for me a few times.

There's also an IRC community at irc://irc.freenode.net/sc2mapster
The place is part of CurseForge, so it has a pro presence - people who wrote some of my favorite addons for WoW. A lot of the focus in the community is on maps rather than AI but the function definitions, etc. are applicable to both and AI people are welcome.
New contributors are welcome, and those folks are pretty good at cleaning up my entries for me after I enter the basic info. Hope to see some of you in irc and as authors on the wiki.
