Improving Student Login Experience: Double logins

[IvonArroyo]

Something that becomes really hard to handle in the classroom is the situation when two students log in with the same username.

This happens once or twice in every study, sometimes they flip the digits, sometimes they forget what their login was. If a teacher is handling this, it becomes really hard to understand what is going on.

Currently there is a message saying: "Invalid Session" and something else on a white screen (give it a try and you will see). What would help a lot is a nice friendly message instead saying:

"Somebody else has logged in with the same log in just now. It is not allowed for the same user to log in simultaneously in two different computers. Note this could be the other person's mistake, or your own mistake. Try logging in again, and most likely the other person will see this same message."
