A month after being renamed I gave up trying to get my old name back.　 I can't save it even though my old name kiyoccc and the name recommended by bungie is also kiyoccc. Next I tried changing kiyoccc to KIYOccc but no luck. Next I changed the name to kiyo@ccc and it worked. I didn't want to change the name I had been using since D1, but I figured it was better than a prisoner-like number and gave up.
