Options include: Students can post and comment, Students can only comment, or only teacher can post and comment. This action can be done for individual students by checking the box next to their name or choosing the whole class. 
The second added feature is the ability for a student to choose to turn in an assignment without having an actual file to upload by choosing "Mark as Done". This means, no more "late" assignments for items such as "read pages 120 - 130 in the text and be ready to discuss tomorrow in class". Once done, they can mark that they have finished that item. During earlier fall trainings before this was possible, we suggested posting these kind of assignments as an announcement. The downfall of that is that it wouldn't show up in their list of upcoming assignments, but the benefit was they wouldn't end up with a list of "late" assignments since their was nothing to digitally turn in! This resolves that. Awesome!
Other features added - the ability to go back and look at comments that were deleted. Also being able to download a csv for all assignments at once, not just one and the ability to sort their list of students by first or last name. These added features make this tool even more powerful in the classroom.
