What forums integrates with Community Builder and joomla 1.0.8

The only three that I'm aware of -- in order of integration completeness:

Simpleboard
PHPBB2
SMF

PHPB22 is what I use -- it integrates nicely, and is a great board.

Could you give me the link to the PHPBB2 joomla/community builder plugin?

do a search

Ok i have downloaded the latest phpBB2 by Przemo and used this to integrate them extensions.joomla.org/component/option,com_mtree/task,viewlink/link_id,524/Itemid,35/
now How do I make sure they play together with community builder? I can't figure out how to get them to do that?
did I pick the right ones?

That's unfortunate - I think Steve meant search on Joomlapolis:

www.joomlapolis.com/component/option,com_joomlaboard/Itemid,38/func,view/id,8528/catid,13/limit,6/limitstart,0/

That is the plugin/connector that will integrate CB and phpbb2 together.
