[aur-general] Registration problem

I was trying to register a second AUR account with my Gmail so I can use multiple SSH keys, but for some reason I never received the password reset email. I've used dcelasun+aur2@gmail.com for the second account, so maybe the "+" had something to do with it? I've also tried registering a third account without the plus sign, but it says my ssh key is already in use. Can someone help please? Thanks.
