Tozzl. Then two weeks ago I had this horrendous experience with TodaysMeet. As a result I'm switching to using Tozzl for most of my backchannel needs. Tozzl allows me to create sections for chat, file sharing, and YouTube videos within one backchannel. I can also import the feed of a Twitter hashtag into my Tozzl backchannel. In the video embedded below I provide a demonstration of how to create a Tozzl backchannel.
