I'd like to pledge 1 BTC, and I've sent it to the address.  Because I don't always check on here often, I wanted to pre-donate for at least the first charity.

My address that the coin is coming from should be 1EXk4cffT2Pr3D1TC7ZL5Xe5aJQgip9SJn

(but since it's the first time I've ever actually sent coins, I'm a little confused since now the bitcoin client is showing a new address for me. Is that just because it generates a new address every time you send coins?  Makes it a little confusing to know what address to tell people to expect the coins from, eh?  Ah, it's probably just me with cobwebs in the brain...)
