This means you will create another username of your own and you once again will decide for the url of it. What you will be selling to a buyer is just the url of the username. Tried a transaction before but didn't push through because someone said its best to use the fragment.com
Let's forget all that. I do not want to sell anything. Especially any account related things. I guess my BitcoinTalk accounts worth some money today because I saw a lot of sold account got exposed and most of those accounts has zero earned merits, but those accounts ranked up with the airdropped merits. I am not going to sell even if someone offers me a couple of thousands dollars, not even if I decide to leave the forum in the future. I will ask the admin to ban it like he banned Lauda and Satoshi and I guess o_e_l_e_o too.
