Is there something wrong with the login system to the website?  I've never had an issue previously, and now I am.

It's saying that my username doesn't have an @ symbol in it where an email address would be required...my username isn't an email address. When I click forgot login and try to use my username + email to retrieve my (not forgotten) password, it says user not found. I've been using the service for over two years...what's the deal?
