You can't. Unless you have a NESSACARY reason why you can't. However I have some options... 1.Ask a mod to just rename your current one-if it's the name that's bugging you. 2.Just leave and turn off email notifications-the user name will just die off. Hope that helps. (and there is no need to make 2 topics in different sections-one is enough-and it would be moved when needed-sorry to point that out )
