I need to change an email address because I can't login to the address

We'd need your handle, old email, and new email. Might be best to use a ticker if you don't want people to know your email (http://support.swcombine.com/), but I am not sure if guests can access that. Otherwise, you could try DMing me, but again I am unsure if guests can do that.

Anyway, once I have those 3 bits of info I can swap your email and send a new password.
