For some reason, on the PM website, when using the Contact us section, when I attempt to enter a form for email support, I cannot submit the form because it says 'email does not match'. I have entered the same email address which I used for PM website, so I have no idea why it doesn't match.
Here's an idea - don't validate the form. Allow it to be sent, and tell the user to expect an automated email response saying that their request has been received. Do the usual stuff and tell them to check their spam box. If they don't receive that email, they know they entered an incorrect email, and they'll enter it again.
That's much better service - you served the person who entered the email correctly, and the person that made a mistake had to enter it twice.
