Good App

On the polls and questions, maybe only make them visible to people who attended your session. Everyone was just trying to get points and not really giving accurate feedback. I had 30 people fill out my poll if my session was helpful before it even happened and before you could watch the recording.

Require people to sign up for sessions in the Agenda so speakers have an idea of who is coming to their presentation because sometimes we need to tweak the session at the last minute to accommodate a different room of people.

Make polls and questions session specific to the session and not add them to the community talking boards where people just look for things to answer for the prize or points. Have a separate area for community polls and questions.
