Great work! I just tested with my account and it found my account's estimated value in less than 15 seconds. 
I do have one suggestion regarding the ads. The top banner ad looks a little out of place, maybe if you centered it that would make it look a little better?
Huh. It looks centered to me. What browser are you using? I do have one suggestion regarding the ads. The top banner ad looks a little out of place, maybe if you centered it that would make it look a little better? But overall great work, the only other thing maybe worth tweaking a little bit is the formula for finding the account value, it estimated that my account is worth ~ 0.12 BTC. I'd estimate that it would actually be worth 0.07 BTC or so at most, since Senior Member accounts seem to be selling for fairly cheap here now ( < 0.2 BTC).
I have noticed the decreasing prices and I will soon adjust the estimation accordingly.
) but I just tested it on Chrome and it does look centered to me now. Must just be a bug with IE.But wow, the queue has sure grown from when I tested it out yesterday - I'm number 461 in line right now. It could just be bots clogging up the site, because it's hard to believe that there are 460 other people waiting on valid requests right now.
