Extermission - Constructive BackChannel

"Extermission" = planned interlude of 1-5 minutes when participants share something useful during a class, presentation, or workshop.  They are invited, especially, to reach out to colleagues who are not participating in that session and recommend some useful resource or idea that has just been identified.  In online events, an Extermission may also be used to invite others to login for the remainder of the session.  An extermission legitimizes "back-channel" communication among participants during an event - live outreach.  See:  Extermission - Frugal Innovations
