Oh Thankyou but it's a 384 page script and that would bother people to read I believe, unless I fixed it to a story, which I could do over the process of a few weeks. Before I'd ever post it up, I'd have to get it copyrighted possibly, but to do that, I'd have to be able to ask for permission from 343I and Microsoft, so here's what I'd need to do.
Fix the 384 page script into book form. Contact microsoft, give them information of the story, send them copies of the files and seek their approval. If approved, they would need artwork for the book, which I can do. So, give me awhile, maybe a year, possibly less if I push it. But you do have a good idea. A fan-made Halo story based forum would be a great idea. If people put their work on the forum for free, than it could possibly make this website much popular because machinima directors would probably hear of this, and check it out for themselves, making a good word for the website.
