Yikes! I missed a day!
Tip # 13
Reminder to self: If you have them, take a stack of business cards with you to the conference. They don't have to be fancy, just your name and full contact info. is all you need if you're doing any serious networking.
If you have a book to promote, why not use the reverse side of the card for the full ordering information, including ISBN, so anyone wanting to has all they need to order it.
And one further tip - if you give your card to someone so they can contact you later, jot a note on it to remind them why they have it in their wallet. I have often get home from events with other people's cards and wondered just what I am supposed to do next.
