Actifan

If you even read StF you'll do. You don't have to be an actifan, just so you read StF.

Really, I seem to have reversed things a little by being a letter-hack after becoming an actifan.

Actifans end up feeling they're being forced to pay for other people's "good time" and realize the mere attendance of these other-media fans means they will have to pay (through increased membership fees) for things SF Worldcons once got for free.
