Facebook LIVE is an incredibly powerful and free means of running a Club Meeting particularly if presenting a high power Speaker to a large (say > 20 people) audience. 
Its major disadvantage is that it is NOT interactive.  It is possible to submit questions as a comment or via email to a member in the room.  For smaller meetings where interaction (conversation) is preferred, Zoom is the best candidate.
