I have been requesting assistance, PM since thread 114!!! And why is this so difficult? What's wrong with a simple sell with authentication? Also have YOU tried to sell? I bet it won't work!!
I don't understand why people do not read instructions. Selling an account is as simple as:
1) Choosing the withdrawal address from your own wallet.
2) Copy and paste "I_sell_account_*******_for_*****_BTC", without quotes, without spaces...
3) Sign the message.
4) Copy and paste the signature.
Every sell request until now has been fulfilled properly. If you can't follow these simple steps I don't know how to help you. Read again the instruction and try, if it doesn't work either you are doing the wrong procedure or the wallet you are using is flawed.
