To contact an event organizer or the owner of a classified ad, just go to the ad and look for the “Contact Listing Owner” or “Contact Event Organizer” button.
Click the button, and a form will pop up for you to fill out. Fill out the form with your name, email, phone, or other contact information, and include a message to the listing owner. Then press the “Send Inquiry” button. The listing owner or event organizer will receive an email with the information you submitted, and they can contact you back.
To RSVP to an event (indicate you will be attending), click on the event page, and then look on the right sidebar. There will be an Event Attendees box in the right sidebar. You can click the “Yes I’m Attending” button to RSVP to the event, or you can click the “See Who’s Attending” button to see other people who have RSVPed to the event.
If you decide later you cannot attend the event, you can return to the event page (find it under your dashboard listed under “Events Attending”), then click the button to “Change My Reservation”, which will remove you from the RSVP list.
