I'm fairly new to wiki's myself, so i'm curious if this sort of interface is possible : what i'd like to have available for any given setting i'm creating is a space where i can post various pieces of the setting, like a bit of detail on a given region or race, a mechanic for accomplishing some task, and having a discussion area (like a forum) just for that mechanic. If the discussion area could be indexed in such a way as to delineate when posts occured relative to edits of the topic being discussed, that would be a nice bonus. Couple that with only allowing certain people to edit, and it seems like it would be a very good tool.
