I don't know why they only have three stars...I used this extension on a site for a company that had multiple events and multiple types of events from golf tournaments to committee meetings. It does everything it needs to and more. AND THE SUPPORT! Fantastic! I had a question that evolved into several questions. The questions began at about 2pm with Michael and ended at 7pm that night with Sushil ! I received responses promptly and accurately! I could not believe I could ask a question at 7pm pacific time and have a response that night! I'll use this module on all my clients that need registration for events! Thanks support team!
