When you go to your schedule and see the "Leave" box, that means you are
in that class. If you don't want to be in the class, then click the
"Leave" button and it removes it from your schedule.
It saves your selections as you make them, so if you log out and back
in, they should still show up. You can export the iCal schedule to
Outlook, if you want to open it there.
I think this is just to give us a visual idea of the classes that we
want to attend. I imagine that we will still have to register for the
learning classes, when we check-in.
Thanks,
