Sure can! Just go to the My Settings section in that blue bar near the top of the web page, scroll to the bottom of the vertical blue selection bar there and at the bottom is the option to delete your account. Sorry if that's sort of hard to follow...
Keep in mind that deleting an account will not delete posts, it will just delete the registration information and prevent you from logging in (unless you make a new registration.) If, for example, you just want to change your name, you can do that by putting a request in to the staff.
Due to some recent issues, self-deletes have been temporarily disabled by the staff. If you'd still like to delete your account, please start a new thread in the Ask The Staff sub-forum letting us know and we'll take care of that for you.
