Yeah, it's pretty simple you just need to set up your signature. Once done it'll follow all your posts. Just click on User CP(that's your control panel), after following that link a new page will pop up with a column of options on the left hand side. Click on Edit Signature and then type in your team info there.

Hey MD, I have a question for ya, I see everyone has there teams at the bottom of there posts. Is there an easy way of doing this other then typing it out ever time. If yes, some advice would greatly be appreciated
