Funny, but when I tried to respond I kept getting 503 - Service Not Available. Eugene, UBB is a memory pig which is why we don't allow multi-forum search.
Anyway, writing a Java forum is not a trivial exercise. Since we all have real lives (and in many cases real families that require part of our time) we simply don't have the time to write a full-featured Java forum.
The only Java forum out there is called
Jive. Jive is pretty good but it does not have all the features of UBB and requires a lot of time to customize. We have a custom version that we have been testing but the problem is how do we convert several hundred thousand posts from UBB to Jive?
