Core 2 Duo?

[Sanuska]

www.good-tutorials.com has a few tutorials for rubber stamps (What the Core 2 Duo sign is). As for the sigs, most the time it's just a picture of the persons computer, a custom downloaded font, and then just the text overlaying the backround. Give me an example and I could help you out more.
