It's easy to use and has a lot of features. It's very simple and organized. The ability to send out mass emails is a great feature. I wish that the scheduling could be a bit more robust. You have to make the appointments and reminders before you can schedule them. I wish that there was a way to schedule the appointment after you've made it. It would be nice to be able to schedule the appointment after it's made. I'm using it to schedule events for my clients. It gives them the ability to create an event and schedule it for themselves in advance.
