I currently have... *checking*... 112 Users referred and earned 4.85 USD from them - just ~2 times more and I get a free meal at McDonald's! Yay!

I really like referal systems like Dropbox + Tradehill, where both the referred user AND the "referral giver" (?) do benefit instead of just benefitting one party.

One fact that I don't like is, that ref-income is in USD. I don't use USD, it constantly looses value against my currency and is imho about to crash - but I always have to wait until there is at least 1 USD in my account to be able to convert to BTC. I also fear the some day I will have 15 US cents, 8 Eurocents, 30 Pesos, 2 Yen... Bottom line: I want my ref-income in BTC - after all, this is a BTC exchange!
Yea I actually used your referral link

I would also have to agree somewhat about the income. It would be better if they gave an option, perhaps, to receive either in USD or in Bitcoins.
