[Typo3] wiki extension - Which one?

[Jay Austad]

Which Wiki extension should I go with?  I noticed a few in the  
Repository.  I just want a solid wiki with decent features, nothing  
that is going to hose things up.

My original thought was to use a knowledgebase extension, but I'd  
rather that users of the site were able to edit their entries and  
make updates rather than me having to admin the thing.
