Ok heres what i have

Joomla 1.5.2 - Installed and running with work already in progress

Community Builder 1.1 - Installed, havent done any work with this yet though

SMF 1.1.4 - Not a ton of users yet.... Installed in a seperate SQL database then J!.... I am reading that I need SMF to be in the same database.

So, that being my situation, how do i go about keeping SMF running, and moving it into the database with J! ?
