What does Eventbrite do well? Eventbrite is an incredibly professional way to organize events. It has a great back-end and allows for lots of customization to make the event look and feel the way you need.
What does Eventbrite not do well? It's limited in the capability and sometimes the day-of check-in options are glitchy and don't work well. Also, it defaults to "tickets" which can be confusing for participants if you are only needing a registration.
What do you wish you had known about Eventbrite before using? I wish I had understood how to truly choose and differentiate between ticketed and registered events.
