@Use actual badge scan instances for being able to comment and/or post anything about a session, review, etc.
Utilize the app subscribed users for a session to adjust and/or change rooms due to capacity issues!
Use the app to pre-register/check-in users who want to attend a session
Allow standby/waitlist if not previously registered in the app
People were annoyed and the lines were extremely long for many sessions, especially for the Champion sessions. This was a huge disappointment! Being turned away from multiple session in a given time block is not an ideal user experience!
Validate either through the badge scanning and/or QR codes
As suggested in the app event for 2016 Summit, create a geo-location service (if possible, but not likely), that can track where the user is to validate that they are in a particular room or session when posting.
Close posting about a session within a particular amount of time (12 hours, more?)
Make sure that the app actually pushes the images to the social channels when posting; Posts show lesser value on the social channels without the context!
