I wanted to add a wiki long ago. The biggest problem is that it seems to be better to have single user sign up and login for both our wiki and our forum.

There are no mods that I know that work with Dokuwiki.

It is possible to use MediaWiki, but the forum script needs to be updated (not an easy thing to do since it has Zoints SEO, Zoints Tags, Anonymous user mods installed.

Another option is to use VaultWiki, but it is a commercial product. It could be easier for vBulletin users, but you never know how long it will be on the market.

New vBulletin 4 costs almost $200, vB CMS (which also has blogs and articles) is even more expensive. The good thing is that it is more secure and allows to fight with spam more effectively.

VaultWiki Premium costs $60

What Wiki do you think we should use?

If anybody is willing to make a donation, I will post a paypal account here. Thank you anyway.
