As many of you know,
One of the many aspects of the fund-raising is a raffle they are running at Arisia in a few weeks, and it is looking downright remarkable. They've gotten donations of dozens of prizes, many of them quite neat, with more continuing to come in. For my part, I've contributed a small stack of classic fanzines from our considerable library of them, including early works by several major SF authors.
If you're going to be at Arisia, you can buy tickets in person there, but if not, they're selling tickets online -- see here for the details. I highly recommend it: this raffle looks to be bigger and better than many entire conventions manage, and it's a really great cause...
