I don't think you should change your username and join again, imagine the cost and effort of copy and pasting your info and buying a new email address, not to mention the cost of joining CS again in the first place.
If you like punk girls, then your username says it all.
If you don't, well....
But seriously, your info is cool, I think you'll do well here.
Just don't waste all that money buying a new email address and paying to join CS again, stick with what you have, everything will work out OK , trust me..

Run that by me again?
