What I want to do is have all my messages (Text sms, IM, and BBM) go into the main message center on my Blackberry Tour but NOT my email. Is this possible?

Nope.

So I would have to make email and text seperate? So what would go into the message center? Just IM and BBM?

Is this a trick question?

Messages ALWAYS go into the main Messages folder. This is not something the user can alter.

you can separate SMS/MMS into their own separate folder - But BBM, Emails, IMs, etc will all go in the MESSAGES folder since they are all MESSAGES
