GPS Registration is allowing two user with the same email address not case sensitive

1. Create a user using any email address. E.g., tsherman@curriki.org
2. Create another user using a different id but the same address but change any letter to a different case. E.g., Tsherman@curriki.org

Bug
There are now two user with the same email address.

Here is the email from Dominique.

I’ve noticed that since the case sensitivity fix was implemented that now users must enter their usernames with the correct upper and lowercase letters as when they registered. This was not the case before…but I understand that.

We’ve had many users complaining about not being able to log in over the last week and so I’ve been looking up their usernames and advising them on the exact way they need to enter their usernames.

One user tried to re-register using the same email address and the site allowed her to do so since she entered in the email address with different cases. So now we have a problem.
