With more that 40 commits in the last 7 days, the developer is doing a superb job. JooBB still need to have more styles/templates. Also, a Last Posts Module is terrible needed.
After waiting and monitoring JooBB development through svn, I am giving it a "GO". I have installed as my default forum.
Thanks the developer and hope other coders will help him, with more styles, addons and improvement to the code.
