We’ve just updated GradeMate to include a new compose mail page, assignment updates, and a slew of bug fixes — most of which you submitted 
The compose mail page now allows you to more easily select contacts from any course that you share. We’ll be integrating a user search in the next release so that you can find other classmates, along with a host of related privacy and account settings so that you can always control who can find you on GradeMate.
Assignments are now sortable by date and name (just click the little arrows at the top of your assignments!) and we’ve fixed some annoying bugs regarding completed assignments.
You’ll also notice that Discussions has been temporarily removed. We’ve been thinking hard about how best to do it, and our next release will include a new approach to discussions: a way to share any type of media or content with threaded discussions from classmates. We’ll also be slowly rolling out a public discussions page which will allow anyone to post any media or content for the general GradeMate user-base to view, comment, and discuss it. This opens the door for homework help when and how you want it, and is one of the first steps we’ll be making in growing GradeMate into a platform for connecting teachers and students within the GradeMate network.
We’ll post more about the discussions as we finalize the updates, and provide some sneak peeks into how they’re coming along shortly!
