Create Student Email Group

The page that follows shows your students' info including emails and the best part is if you scroll all the way to the bottom, you see them all in a box from which you can copy and paste! (I prefer the 'triple-click to highlight all, Ctrl-C to copy, Ctrl-V to paste' method myself.)

The document below details another way, but I haven't found a way to easily copy them all the email addresses at once like the method above.
