DS9 belongs to http://teacher.scholastic.com/writeit/. He has written/directed and edited two short films as part of the 48hourfilm.com project and is currently writing a feature film about religious persecution.
I would definitely find a site for registering his work as he goes. I will try to find one and post for novels, with screenplays strongly recommend the WGA.org site (Writer's Guild of America) I do not think it has an option for novels but you could check.
