I can't quite get PayPal to take my money. Will donate small amount when able.
Another thought occurs: what about a sponsorship? That is, not an advertiser but a corporate host who gets the right to say "Magic Duel, brought to you by Cadbury's Chocolate Underwear" or something like this? Big tech companies or MySpace will be looking for the next big thing in online community... They provide all the server space you need, no advertising is present, you just have to go through their page to get here.
