a. mandatory to state question
b. when asking question from Q&A tab (option to raise hand)
When user raises their hand, ask to put question

• Show the question in the Q&A also
• This would reduce spam hand-raise and help qualify the people HOST brings on stage
  Currently a problem, as no one wants the bring unqualified people on stage
  (Issue: usecases, where org using this to bring people on stage, and not really for Q&A.)
  Alt: give a hand raise button, in Q&A itself (so use can ask a quesyion and raise hand
