Questioner

Questioner, along with Organizer, is a Q&A platform intended to be used during the Question & Answers section of an event such as a speech, a conference, a class etc.

The way it works is very simple. First you create an event on Organizer. Then you use the event ID (form Organizer) in order to register to that event via Questioner. At the end of the event, during the Q&A section, participants can pose their questions to the main event organizer (for example the speaker, or the professor if it's a class) via Questioner. The questions are gathered as a list for the event organizer to answer. Additionally, participants can up-vote or down-vote any question, promoting the questions they think are more important and should be definitely answered.
