I've decided on the last date to donate: >1 BTC donations before or on September 2nd will get the beta!
So people who donate 1 BTC won't be getting it on the 2nd? Or do you mean >= 1?
Stupid question, just send 1.00000001 if you are really worried. wasting your time asking this over 0.00000001 BTC shows that you really have no concept of the value of BTC.
