Don't you wish you were the first to have thought of Youtube? Well, you can't really change the past, but you can certainly plan for the future, especially with PHPmotion. It is a open source PHP script designed to allow users to share their videos with others on the Internet. Users can then add comments, vote for their favourite videos and even share music. With a good number of freely available templates, the site design itself can also be interesting to attract visiotrs. They provide support to their script through the forums.
