The Future of the Wiki and Forums

As everyone probably already knows, registration in the Wiki and Forums is broken. Today I tried to upgrade Tiki (the underlying software) to the latest revision, but that did not fix the registration issue, creating new issues instead. Now that I’m sick and tired of this big and ugly whatever named Tiki, I’d like to get rid of it as soon as possible.

I propose the following alternatives:

• get rid of the forums and replace the wiki part of Tiki with MediaWiki (or something else that seems to work well). From my experience with other projects, MediaWiki seems to work well, so I’d like to go that route. Instead of the Forums, people should use the mailing list (which works for other open source projects as well, so why not for us).
• keep both the Wiki and the Forums, and find reasonable alternatives for both (e.g., MediaWiki + phpBB). Problem: converting all the existing forum data to the new forum, which is a nontrivial task.
• have someone (definitely not me) fix our Tiki installation.

Any opinions?
