Email address already exists

Well that is weird. I never knew the email address was case sensitive (and, I don't think it should be). But I was able to create 2 Users with the same email, but different case, and it worked. It's a little strange though. I haven't fully tested this, but it seems if you have 2 email addresses the same with cases different, then case matters when you enter your email, but if you only have one email address in the system, the case doesn't matter when you enter your credentials. Also, when I tried "forgot password", I received 2 emails to reset the password (each addressed to the names I entered for User.)
