You’re absolutely welcome to share your film, filmmaking product, or festival here, as long as it’s genuinely related to helping filmmakers and you include clear details about what it is, who it’s for, and how it helps. When you post, think of it less like an ad and more like an introduction to a useful resource: explain briefly what you’ve made, the type of filmmakers it serves (students, indie directors, editors, etc.), and a concrete way it can make their work easier or better, and staff may ask you follow-up questions to help everyone understand it more. What project are you thinking about sharing first?
