The same old story a newbie opens a new account and to just post some thing starts a thread with useless information and then just leave it to die, and then all campaigners come and start to troll the thread with post.
IF the OP want then he can open a new account with the desire name.
Surprised to see someone saying something like that having a signature himself.
Anyway, @OP, you are not a having a really big rank or position that you can't leave your recent account, so simply leave this account and create one more with your desired username and start surfing then.
Enjoy.
