In case this is just about changing your account name...
Just a suggestion (and at the risk of sounding like an Ad-Bot): You 'could' support NG for a single month (for $3/$5), change you account's name, and permanently unlock some features even after that month has ended (like the chat). That way you could keep all of your submissions in one place; as well as your inbox, hard earned voting power, your reviews, and your 'account age-bragging rights'... ;)
