This is my first year hosting and I have three classes
 I was wondering if there was a way to check how many people have ordered tickets for my events?

You can either look up the events and see how many tickets are available, or you can look up the events through your EO/GM Dashboard. You can also see the names of the people who have purchased tickets.

There is one other way that may be new this year. Click on your name at the top of the page and you will see a listing of the events you have tickets for, it will also list events you are running and how many tickets have been sold for each one.
