50 BTC! OMG! 
Are you serious really? Please consider them for a discount. Paying 50 BTC should have been possible in early 2010. 
Yes, 50 BTC. The price should not be adjusted and it will always be the same. The USD equivalent is a pointless measure. Are you serious really? Please consider them for a discount. Paying 50 BTC should have been possible in early 2010. BTW, why is it restricted here? Is changing a name really bad? I have been on other forums and I'm easily able to change my username and also the previous username histories are shown! Please tell theymos to help me out! 
Because of various problems, like impersonation, scamming, etc. Theymos will definitely not answer your call for help as the username change is requested without a proper reason.
