This might do well in the 'elements' thread, too... One of the things that I've neglected thus far in my planning for the expo booth is, once I've got a potential customer's interest, how do I take the next step, get their names, addresses, phone numbers? $? Guest book? Prize giveaway (though I don't like this idea too much - give away something for free and all you get are people who expect things for free)? Any ideas/experiences out-of-the-box?
