hi gibaphp.
plzXoo looks like a forum you want.
I don't like a forum which the first poster has special privileges.
Because it cause too many threads(topics) which has no replies.
XUGJ applied plzXoo as Q&A forum, this system gives many stresses from selfish questioners to answerers.
Now, XUGJ uses d3forum, and all answerers are free from stress.
Anyway, I thank you for the requests.
Though I've never used CBB, I'll make it if many CBB users want d3forum.
It is not so difficult to implement the converter ... perhaps
