I'm looking at integrating a forum system with a project that I intend on writing. In order to avoid having to mess within the forums database, I was hoping to be able to have two seperate databases. However, this would mean that my user information (I'll need to expand upon the forums information) will be spanned across two different tables in two different databases. Will this cause problems in accessing. I haven't gotten real indepth with mySQL past your standard queries, so this is entirely foreign to me.

I understand that I could just use the forums database and extend my information in the user table, but I would like to leave the message board stuff completely untouched (in case there needs to be a switch for some reason).

As usual, I would greatly appreciate your help! Thanks in advance!
