whats a good program to use to make awesome sigs like all you cool kids on here?

I recommend GIMP if your looking for a free program - http://www.gimp.org
Photoshop is better but its pretty expensive, you can download the 30day trial for free i believe - http://www.adobe.com/products/photoshop.html

thanks i downloaded photoshop trial today and quickly found out im terrible at this...hopefully i will get half decent before the trial is over
