I made a few dozen business cards with my name and contact information on them. They're cute. They have little tree (as in family tree) pictures on the left side and my details on the right, including a shout out to the We Tree blog. It beats writing down all my information for everyone I meet.
On the back side of the card, I've listed the top 20 surnames I'm researching. I think it's a pretty good idea, if I do say so. Marketing skillz: I has them.
So if you're going to the MCGHS seminar on Saturday, come say hi so I can give you one of my fancy surname business cards.
