You can use a service like Eventbrite among others for no cost. We can link to your sign-up page, donation page, or ticket page from your Event Information listing. We can make make a private duplicate listing and make you the host, so you can link to the page of your choice and/or gather RSVPs using our tools. If your film has its own Screenings page on Bullfrog Communities, you can list the screening yourself, including a private listing.
