If you mean that the website automaticly checks if the submitted file is OMR compliant: no, it doesn't. I'm not exactly sure how to implement that either. But, how it is now, is that there are a few people (although, at the moment it's only me of course) who can login to the admin-interface and add files submitted through the forum or something like that. There isn't a way for users themselves to add files. I could do that of course, but then again you need someone who checks if the files are correct.
