Computer Science and Open Source Technology (OST) 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 beyond the level of an end user). I'm currently using Wikka to host the course notes and other miscellaneous items for the OST program. 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 migrate my Wacko pages to Wikka. The code is documented, so I won't bore anyone with the details.
