The domain in question is one I just registered tonight. There's no danger of losing anything, but I didn't want to back myself into a corner and find that I had done something irreversible. I wasn't sure how Gmail handles transfers away from them (don't they do something weird when trying to close an account?) so I wanted to make sure there wasn't a policy in place preventing such a transfer. Similar to the inability to forward mail to AOL and Comcast that I read here.
The subdomain idea is very cool tho, in case I need it in the future for some reason.
Thank you for your help.
