Josh, if I am not mistaken, I think Edhead is the only one that can change your name for you, It seems like he did it for a guy on the Ms board. his name was spiderrigman had over 600 posts and changed it to crappie cowboy and kept all his posts. I don't know the details involved in it. But like FM said it would be easier to just create a new account. You have 29 posts so far, so you wouldn't lose too much and it wouldn't take you too long to get your rank back up.
You can't fish with a hung line!
