Ok, I dont know if you can see this or not, it being on not my own computer, but here is my attempt at a sig I have been working on the computer I am working on now. (It doesn't let me see pics for some reason :/) I got GIMP from seeing the works of Lockdown, who gave me my own sig, but being really new at this, I decided to paste my first work. Here you go.
Too big to my likings, and well, its not very good. But I want to help. Look up Gimptalk on Google, then search GIMP sig tuts. Those will help you alot.
