Adobe Connect 

The Adobe Connect service is currently (January 2017) under review, and may not continue to be available, so it is recommended that no new users start using this software until after the review is completed in the Summer of 2017. 

Adobe Connect is web conferencing software that allows you to deliver lectures, seminars or presentations online.  You can share PowerPoint presentations, videos, documents and you screen with participants.   Interaction can be done via audio, video and instant chat.

The following video presentation gives a good overview.
