This free application is marketed for video conferencing but is very useful in the class room. With a free account, instructors can schedule live meetings with multiple students, can post pre-recorded MP4 videos in D2L or in YouTube without having to convert the format, can easily switch between screen sharing for them and students to answer questions, and can record their classroom lecture and post it in D2L immediately for online students to view (if they are teaching multiple sections). It can also be used to schedule departmental meetings when everybody can't meet at the same place but can meet at the same time.
