Zoolink includes a great way for you to generate an ongoing revenue stream.  Simply invite an association or event organizer that you know to create an account using your personal link (accessible from the setup menu once you have an active account).

This account will be linked to you, and you will receive a percentage of all revenue generated by/through this account.  Sit back, relax and receive quarterly payments.  The more organizations you successfully invite, the more revenue your organization will earn.
