pantsmail - Pantsmail is infrequent email about whatever I happen to be thinking about when I send it. You should sign up because you will love it. Everyone else who signed up loves it. Everyone.

tradeshow - If you sign up for this tradeshow mailing list, you will be the only person subscribed to it. So that would be kind of weird. I'm not saying don't sign up, just that it would be weird.
