Update May 12, 2019: ThinkBinder is no longer online. 

Think Binder is a new website that gives students a place to create online study groups. In each group students can share files, share links, chat, and draw on a collaborative whiteboard. Students can create and join multiple groups. As you will see in the video below, getting started with Think Binder takes just a minute.
Embedded below is my brief video overview of Think Binder.

Applications for Education
For students working on group projects, Think Binder could be a good place to organize their findings and hold brainstorming sessions through chat. The collaborative whiteboard space could be helpful for drawing diagrams of ideas for group discussion.
