Don, you're never going to get complete consensus on this issue.
We definitely need a forum for designers and administrators.  We definitely need a forum for end users.  I'm not sure if we need a forum for evangelism -- but it can't hurt, and it might help a lot, especially as OpenACS begins to gain ground.  (And besides, such a forum is almost mandatory in the open-source world.)
The existence of these forums has been debated long enough; it's time to take action, and then fix whatever problems might occur as a result.
