To set up a video meeting you must view an attendee's profile and select Schule a Meeting. That attendee must have selected their availability during the conference for you to select a time to meet. In order to allow others to make video meetings with you at the conference, you need to select times you are available to meet under My Dashboard > Vcards & Meetings > My Availability. Once you have selected these times, other attendees can send you meeting requests based on your availability.
