An Event is a calendar event, with a date/time and location - which you can optionally include RSVP under 'Signup settings' which can record name, email address and phone number. You can also upload and attach a flyer. If you are entering a Location, ensure the street address is correct and as complete as possible, this will improve the accuracy of the links to the 3rd party mapping sites. You can manually place a marker on the interactive map when creating the event.
If the 'Semel Institute' audience is selected (under 'Groups'), and is 'Public,' the event will also be listed on the Institute website front page and main calendar.
Consult with the site administrator  as to how your calendar is rendered to the public - it can either be a browsable calendar, a scrollable timeline or a list of upcoming events.
