Class 10: Facebook Events As An "Opt-In" Form of Collaboration

These are screenshots of me joining facebook events and sharing. 

 I joined the Facebook group located at https://www.facebook.com/events/1432080547091871/. I opt-in  by  simply clicking the "Join" button! I then shared this event by clicking the "invite" dropdown box and selecting the Facebook group I'd like to share it in.
