Do you want your member profile completely deleted or just edited? If just edited, you can do that yourself. But you cannot change your screen name. As a moderator, I can do that (just tell me what you want to change it to here or send me a private message). That will also change the screen name on your past posts. I can also delete your profile if you want. If you change your mind, it cannot be restored. You will have to register again.
Let me know.
