209642 Joomla Chat and MessageBoard

I need an experienced Joomla person to go to [login to view URL],com_mtree/task,search/Itemid,35/searchword,chat%20room/cat_id,0/ or you may have another FREE module or plug in. I am looking for someone to install: 1. a Chat room that supports multi users at the same time. 2. a Bulletin Board (phpBB or Fireboard or ?) I want users to only have to register 1 time and be able to use the same username and password for both the Chat room and the message board.
