Once you have the image codes for your banner for use.. example:

Code [img]http://i42.tinypic.com/2i77r7o.jpg[/img.]
... you MUST select the "Preferences" section in your profile, and change the selection from no to yes. That way once you put something as a signature it appears everytime.
G-G, I think you had a signature, and I tried activating your signature, but for some reason the code disappeared, so if you can, try putting something or the code you put into it in the sig box again.
