[Inbox] Email (message) multiple classes at one time

[emalates]

Instructors often want, or are asked, to share news and information of importance to all our classes.  Currently, that means copying and pasting that information into anywhere from 2-5 different classes.  Given that there is a drop down box for choosing a class to message currently, adding the ability to select multiple classes seems like it would be an easy "fix".  Please add this capability ASAP.
