I'm sorry, but currently there is no way to change your email address on the Community site. You'll either have to forward from your old email address, or setup a new account. If you haven't actively used your old account yet we can delete it if you want.
Is it possible to change your email address in the linux mint community site yet? I haven't used my profile much so could create a new one, but it would be better if I can just keep my old one and change my email address.
No, sorry. The Linux Mint developers can but work on a number of tasks, and you may understand that Linux Mint releases and software get priority. A number of improvements were implemented on the Community Site by Clem about two months ago (like easier search and new statuses), but this one was not amongst them.
Fair enough, I'll just create a new profile. Developers efforts are much appreciated as Linux Mint is very good - I'm liking the Cinnamon RC very much.
