I'm not sure this is a feature request so much as me thinking out loud. Forums that last long enough become deep repositories of information, if not generally then at least for the forum's members. The problem is that long threads can be hard to navigate especially for newcomers. Perhaps an on-board wiki could be useful for organizing the community's collective knowledge. There could be a way to link between wiki pages and forum posts, and perhaps a way to archive a thread as a wiki page.

This might make more sense as a plugin.
