I created this signature template (same one you should see below) that you can alter using Macromedia Fireworks.

Alter the background color using the hue/sateration on the background.  Replace all the names with your name and clan tag.  replace the website, etc.  The guy is an assault guy (my best kit, but you can simply replace with your own fav guy/kit).  I hope you all like
