picture it, photoimpression, paint, they are all very easy programs to use, it usually takes me a couple minutes at the most to do up a sig.
another thing, if you want some help, you should tell us what your interests are, or what you mean by cool, we don't know your definition of cool. LOL.
haha trust me I've tried my best at photoshop and everything and I just do not get them....My interests include Kansas Jayhawks, Kirk Hinrich (#12 on the Bulls), and Beer. lol those are cool.
