Dear Craig,
May I suggest you to make only the absolutely necessary changes now and to try something new in the spare 25th hour... the wiki.. OK not new I know... Let me at least put a few notes of what I think might be useful.
The wiki Steve was kind to set up has a zillion functions, but I think maybe 1% of them are really useful, and maybe 0.1% is enough to work - and most of it you already have - e.g. here in the Forum. They IMHO are:
- create new page
- edit existing page, preview and save (requiring a note for each save for revision history)
- store old versions of page (plus have the possibility to revert - but that's enough if the admin/moderator has it)
- be able to insert links and other editing elements - html tags are just fine (the wikish are no better)
- have an automatic "backlink" list (each page contains a list of links to pages referring to this page)
- be notified about page change if required (not necessarily by mail)

For start, this is enough... What do you think?
