The piece will be reviewed, and, if it adheres to the basic guidelines and criteria, it will be posted in the guest writers’ section of the site. This promotes meaningful, articulate, and informed discussions about film.

They also plan to support independent film at its roots by showcasing the work of film students around the world. They have been inviting film students from all schools to submit their work to be shared on IndieMovies Online.
