You might just want to reregister under another user name (maybe not a good idea anyway to use your email addy as your user name---we "Catheites" are not the only ones on the internet.;-) ). You'll have to start out your post count back at 0, but better now than once you've amassed mass quantitites of posts,LOL!
If you're afraid people won't recognize you with a new handle, put "formerly XX" in the sig line for a while.
