If you registered allied, then requested and got a your registration changed to axis by the CM's, you aren't going to be changed back again. It is work for us to change a person's registration. We except the vast majority of people to stick to the side for which they register. For the occasional person who requests a switch of their existing registration, we usually accommodate it; but asking to switch your registration back and forth multiple times is just jerking us around and creating needless work for us, and we don't accommodate that.
