separately to threads, each subforum should have a wiki. a wiki consists of pages, each with a name and content. the page content is rendered in the same way as content of posts in threads, which is potentially more convenient than using a different wiki with a different markup format to store persistent information.
ideally, past revisions of wiki pages will be stored.
access to wiki and ability to edit wiki pages is controlled via permissions system. this means that this feature can't be fully implemented until permissions is done. however, most of it probably can be.
