Sept 5 - Buy business card templates at an office-supply store and print your own genealogy cards with your name, e-mail address, and the surnames and locations you research. Hand them out to fellow researchers at every opportunity.
I used VistaPrint (vistaprint.com) and during one of their promotional periods, I received the backside free. I put my contact information on the front, name, address, email, phone numbers and then in alpha order, I put all my direct ancestor's surnames on the back. I purchased a box of 250 cards and whenever I make contact with distant relatives and we send (snail mail) stuff to each other, I enclosed a card. I keep a few in my genealogy stuff and my laptop bag, so when I am doing research, I can easily share my contact information with others. This box is lasting me like forever, so the cost was well worth it.
