Let Organizer initiate voting process without suggesting meeting times. Let a key participant suggest meeting times
Let the organizer begin the voting process without suggesting any meeting times. Allow for one of the key participants to define the meeting options.
This is really important. I use the tool and when a participant suggested a new time slot (which I actually didn't want him to do it) I was not notified by the system. The meeting then was waiting for me to vote and I didn't know.
