OK, so I'm either going mad or there really isn't a place where I can change my email address for notifications and such. I'd really like to as I used an address that I don't use much anymore to sign up. I'd like to change it to my current address, but there doesn't seem to be a way to do this. Maybe somebody could point me in the right direction -- either that or the admins could add a little button so I can do it myself.
