My co-administrator logged in correctly but was then directed to another classmates "page". Names are not similar, nor login info. Any reason why this may have happened?

Hmmm. Never heard of that one before. Possibly something to do with a cookie issue? I wouldn't think so but that's my only guess. I just tried logging in as both Admins and everything is working as expected. The bets method we have of possibly understanding what's happening here is have him repeat the problem while Jing records what is happening on the screen. Then we can see exactly what he's doing and exactly what he means by being directed to another Classmate's page. Jing is free and super simple and can be downloaded here: http://www.techsmith.com/jing
