I use CS as well but with a few plugs.... Eye Candy has some wonderful effects, So does KPT Vector Grafics. These are filter plugs that can help motivate those ideas in your head. Good luck, your sigs look great.

I went onto adobe's website to see how much photoshop would cost and it was a whopping $650!! I mean I really wanted to try it out and stuff maybe make a few sigs, but i mean $650!! Do you design team members really pay that much for it? I even try to download the free sample, but I don't really know how to work winzip . Do you guys use a different program or get it a different way?? I would really like to know.
