fabs,
I guess to start I would not read much into this board being created. CB has not officially focused on phpBB. This is just a board to group comments and questions on the phpBB Connector plugin that Martijn and I had written.
I will try to answer some of your questions you had (you both beat me to posting on the new board)
2) The phpBB Connector does not require any other bridges to work. It only requires Joomla 1.0.x, and Community Builder (1.0 RC2 minimum), and of course a version of phpBB (full version NOT phpBB Component). It has been used with phpBB 2.0.17 thru 2.0.20.
3) Currently version 1.0.3 is under development but version 1.0.2 is available in the beta downloads area (moved around since 1.0 Stable came out). Version 1.0.2 or newer share logins with CB, does not hack Joomla, CB, or phpBB... only fixes one minor error in phpBB. It also shares updating of usernames and passwords. The full phpBB user profile has NOT yet been ported to this plugin NOR the administration of phpBB. Also phpBB is not integrated into the Joomla modules/components since it is not hacked. So a URL link or wrapper link will need to be added to a Joomla menu or link.
4) does not interfere with CB or Joomla but does require phpBB to be installed into the same database and website as Joomla.
5) Maybe a little bit of a dream but I don't think it is out of the question... will just take time to get there. (Not sure how to get phpBB full version to look like a component yet though except through the wrapper)
Hope this helps. When I get time I will post some of the other top FAQS about the connector...
Enjoy the new forum,
Greg
