Nothing right now... we do of course greatly appreciate every single donation we've received, but currently it's a private thing. I'm a little worried about changing it for two reasons - one, I don't want people to think they're buying anything - a true donation is just a donation, not in exchange for anything (other than maybe happier developers!). Secondly I don't want anyone to get any egos going on the forum about it, as in "I'm a donator and you're not so I win the argument" type things. What do you think?
