YO Teach is a fantastic new site for creating a backchannel chat that I just found out about from the amazing Richard Byrne. YO Teach is a very user-friendly tool to use to create a backchannel chat by simply creating a room and then setting a password. Students can then join via a URL, and the admin feature allows educators to set privacy settings and moderate users. Finally, students are even able to draw on a "scratchboard" and have that show up in the backchannel. Backchannels are a great way for educators to encourage discussion and can use it in a number of ways (i.e. discussing a educational video in real-time, note taking, etc.).
I highly recommend checking out YO Teach by clicking here.
