Text Messaging Signatures

I want to remove my signature at the bottom of my text messages - how do I do this? It is driving me nuts!

Its been a while since I did this, but I believe you need to go into the Settings-> Text Messaging, or its in the messages's area on the menu. Look for Signature under either of the 2. Then just go in and delete whats in there, and it will no longer show up on the Text's
