Hi guys I just joined the forums and I'm wondering where can I get one of those sigs where there's text that says something like:I am the Rogue, I am the Warrior, I am the Assassin...

Click on your name on top of the page, go to Settings, there'll be a Signature tab on the left. But new members can't have signatures or post links, so you'll need to write a few more posts first.
