I think someone else brought something like this up once before (or maybe I'm a nutcase and am trying to remember things that never really happened
) and I think it's a great idea.
Like Jess said, you can print cards off from Vista, but if anyone wants, I can create a graphic image to print your own business cards at home. I think Wally's and of course any other office supply store sells packages of blank business cards that you can use on home printers.
I love this idea!
