Uppercase in email address

[PhilHudson]

I think your advice (create/use a new/different email account) is unnecessary. I believe that the standards for the email protocols (SMTP, POP3, IMAP) specify that email addresses are case insensitive. In other words, your users simply need to re-enter their email address in all lowercase.

EDIT: Come to think of it, if my theory is correct, it follows that you can safely convert the given email address to lowercase in code.
