Skepticon is a free conference, and a recognized nonprofit (so donations are tax deductible). If you have means, you can help people who don’t have means attend a major and fun atheist conference in the buckle of the Bible Belt where it’s most desperately wanted and needed.
They are half way to their budget target, and now need help getting the rest. There are a variety of games you can participate in, where donations can make something happen that you might find interesting or amusing, and a hundred bucks or more gets you a “super secret awesome gift” (although I have no idea what, so I can’t vouch for how awesome it actually is). Or you can just give a little. Anything. Details here.
In fact, if you will be attending Skepticon, and don’t really need it to be free, then just pay what you think it’s worth and you can afford. Even if it’s just ten bucks. Or twenty. Or fifty. Or totally TAMinize it and give five hundred.
I will of course be speaking and drinking at Skepticon. Among many other awesome folk. Those details here. It will be an awesome convention, as it has been every other year before. Help make it happen!
