We work a lot of with independent/non-professional organizers since they need tools that are a) affordable and b) are simple/do not have a large learning curve. Their events include everything from conferences to food and wine tastings.

Event app wise, we have all the features you'd expect (event info, social integration, attendee profiles, etc). We also have some unique capabilities given that we handle ticketing/registration as well. Not to mention, it's completely free compared to $1000s.
