To configure the default event types used in the application go here:

Log in to DJ Event Planner -> Setup -> Application -> Event Form -> Event Type

Please note that on several of the configuration pages, the event type list is based on two things:

1) The default event type list
2) Event types found in your event database

To explain further, say you have an event type of "40th Birthday Party". Even though it may not be listed in the event type configuration setting, it will appear if you have one or more events in your database with the event type of "40th Birthday Party".
