I have searched all over and messed with phpmyadmin all night trying to get these two into the same database so I can convert phpbb to fb. I tried importing the SQL file into one of the databases and I get this error:

#1044 - Access denied for user 'username'@'%' to database 'databasename'

Okay, for everyone's info--I found out the reasoning for the error is because I have hosting through Godaddy, which means also that I don't have permissions to perform this through their control panel. In addition to this, since I use a shared server through them, I cannot use SSH [rather than myphpadmin] to perform the action.

Therefore, the solution I came up with--switch hosting providers, backup all the files from my current site, upload to new host/server. I'll let you know if this works.
