This morning a teacher contacted me looking for help managing desktops in mission control. For those of you like me who wind up with more windows open than you can even imagine by the end of the day, utilizing Mission Control can help you to make sense of it all. As a result of the inquiry, I created a new page over on my "Guides & Tutorials" site to walk you through it. Click here (or on the icon below) to go check it out!

If the student is showing up as red in your gradebook though, you can hide them so you don't have to worry about them. Here is a screenshot to help you do it:
