How to categorize your uploads. First look at the Seven top major categories. If the general theme of the upload falls into one of the top seven major categories then look at the categories under the theme to determine the category the upload belongs into. As in any system there will be cross overs. The file format could be DVD, but if could be a feature film. It could have been a made for TV movie, however, it is also a themed movie. This won't help in the determining which type of gay porn movie, but it will help in what is not a gay porn movie.
