Aha, thanks!

I'd recommend either a) finding a way to send the confirmations out as a batch after the con, or b) making sure people know they need to hang on to their paper receipt for a year. As it is now, if there's a problem with a registration, there's no way to know until you get to next year's con, and anyone who paid cash could be out of luck.

Can we email reg@arisia.org for individual confirmations?
