I found a nice little site that you can all make your own signatures on!
http://freeforumsigs.com/ffs6/Just click on "Signature Maker" or you can mess around with the glitter text and what not. Anyway have fun with it!
*Reminder* Make sure that when it asks for signature size you put 500 by 150 at the very maximum. Also you could probably just type Free forum Signatures, or like free superhero signatures on google and get some that people already made. Just
MAKE SURE they say you can use them. I don't want any copy write problems or anything.
Also here is a user Bar maker. (Kind of like a mini Signature)
