Multiple Stuff on one MySQL Database

[scorpio]

Hi, I run my high school band's forum and I was wondering if there was a way to run Coppermine on the PHPBB database so accounts in one would exist in the other without something screwing up? Also, would something bad happen if I had two PHPBB forums running on one database?

Thanks.

Another question, the server I use runs Ensim Pro 4.0.3, I was wondering how to set up email addresses with the domain name that just forwards without saving anything to the server. Thanks.
