The bookings / reservations system can be easily setup to provide a means for arranging meetings or conferences enabling web users to sign up for a meeting. Payment would usually not be required so the payment engine will be switched off.
An email verification link will be sent to the web user confirming their participation. The order is then set active and the person is added to the list. You can set the amount of people that can attend the meeting all the usual booking options can be applied here.
We recommend that you view our examples page to see how this is setup along with other common scenarios.
