Yes, reporting either post would get our attention, but since I'm here now we can skip that part.
So most of the time it's not really needed to delete an account, you can just not use it. But if you really want it gone you can PM Scottina06 or JanetH our handy dandy Admins and ask them to remove it.
As for changing your user ID, again, the Admins are your friends. Scottina06 or JanetH will be more than happy to change it. Just PM what you want it changed to and they'll help you out.
