OK let me rephrase that. Is there anywhere I can get a professionally made signature for free? Meaning I create it.
If you mean you want something similar to what AC creates, photoshop or another similar program would work the best. I'm not sure the process AC uses, but I don't think it's as simple as "put in text, select image and colors, done" and would require at least some basic photo editing skills to use.
Heres a simple simple signature you can create for free.(like mine) www.textcraft.net Sorry, I don't know any free professional signature.
Sorry man, but I don't think there are really free to use programs to create professional things easily I recommend GIMP, then. It's free, and you can do a lot with it. But it's not easy to learn. Nothing professional is easy to learn, really.
