The Topics tab is where event topics can be selected for custom printed program guides, so that attendees can identify which events meet their interests. A Topics tab for a sample event is seen in the next screen shot. 
The Event Topics Dictionary is a flat table that drives these choices, and the MasterCodes that correspond to the sample topics above for the Event Topics (EVENTTOPIC) GroupType are seen in the next screen shot.
Since our sample event is from a sample annual meeting for NOAH AMS users, these topics are related to the NOAH system. These topics can be customized to correspond to any topics of interest your association covers in events that are listed in a program guide.
More information on Event Topics is found in the Event Tabs and Functions section of the Meetings section of this knowledge base.
