The lobby will receive as input the connected accounts/users as they join in. Each user will have an acceptance variable that will be toggled on or off (when the admin decides to do so)
When they are waiting to be accepted the message displayed should be something like "Wating for admin to accept you"
After accepted they will either: no longer display in the "lobby tab" or they will remain there with a checkbox. The second option covers both the cases of someone joining the GA with delay or someone having to exit during the same.
