I was messing a bit around and i created a new user from a command line instance on a remote server like this:
then inserted an account name ex: name
I went to my wallet on my windows machine, added the contact with another name with
wallet_add_contact_account anothername "BTSX....."
and registered the account i just created from the GUI selecting the name from the directory.
Well... now my new account is registered on the blockchain with anothername...
How's that possible???
