I have a forum in the “playing” area, for discussion of IFComp games:
http://www.intfiction.org/forum/viewforum.php?f=32
Here’s the announcement on RGIF about IFComp discussions:
http://groups.google.com/group/rec.games.int-fiction/msg/1434bc1734b8454d
Later (when the competition ends and the chatter dies down), I’ll probably make a “Competition Game Discussions” folder and move this as a sub-forum inside that. For now, I figured it would be easier to use if it was listed on the main page instead of behing “inside” the competitions forum.
