I originally bought the lower tier to see if this system offers the functionality I'm looking for when putting on an event. This system does everything I need, and more. It's easy to configure, and create the registration site. It handles online, off line and hybrid events as well as handle the sponsors, exhibitors, attendees and more. At first I logged in to see ease of use and was able to set up most of it. Then, I attended a walk through presentation, and saw that I had only scratched the surface. There is just so much more I can do with this. I see now that I should get the highest level in order to take full advantage of this offer and save on the regular cost for attendees. If you're in the biz and you're looking for a full service system that will handle every single aspect of your event, I highly recommend you get the highest level.
