I will try to answer all questions here, all hero accounts are for sale for 0,04 btc, and the senior i will sell for 0,03 btc, after you send the money you will get acess to the account and with it will get the zipped adress soo you can import it.... i wont send the email because you can easy change it at account related settings....

No more information will be displayed, name or total posts....to avoid be tagged... wich wont allow you to join a signature.

If you choose to deal with escrow it will be choosen here at bitcointalk, you will get the confirmation about the accounts being hero or senior and their staked adress nothing else.
