I'm the coordinator for the Computer Science and Open Source Technology programs at North Lake College in Irving, TX.  I've worked my way through several versions of the Wakka->Wacko->Wikka progeny line.  Wakka dead-ended on me, while my Russian never did get any better with Wacko (no, I don't speak Russian, which made it very difficult to work with Wacko).  I would like to see, at some point down the road, a merger of the best of features in both Wacko and Wikka...I believe both have their strong points, and it would be such a waste to see features in one lost on the other.
I wrote a perl script to 
MigrateFromWackoWiki migrate my Wacko pages to Wikka.  The code is documented, so I won't bore anyone with the details.
