It's now possible to use your email address OR your username to login.
Too many people were emailing me saying they can't login, and when I've looked into it they've almost always been using their email address where the site asks for username.
Now you can use either, as long as your password is correct
Worked for me. Email address longer than username though so will be sticking with that till the alzheimers kicks in. Thanks again Mark. I mean Matt.....
