forum account

I want to change my username but I can't so I have to create a new account. But I can't find the option to delete the account (it was there in the previous forums).

Hey everybody! I am lost and can't figure out why my computer does this. Hoping you awesome guys can help me out. So the most accurate info I have, is that the computer just restarts without warning. I don't get a "Restarting" screen or anything. The computer just shuts down, and then starts up...
