TDE is just about the only desktop environment that does not have an online forum.

That could be because some of us prefer the simplicity and functionality of a mailing list with a simple, searchable online archive, like we have now.  Newer and flashier isn't always better; in fact it's often a step backward in every way except fancy looking screens.  And that's without even considering what's already been mentioned, the additional cost and work load of a forum vs. what we have now.
