Only invited users can submit new products (until we don't launch the public submit feature) manually at the moment, but you can always email us. Submitting new products is totally free and we love to add new products.
The first thing is we feature videos that are uploaded to YouTube. So if you have your video on YouTube, just send us its link and the products mentioned in it. We can't guarantee that it will be added to the directory, but in the most cases we publish submitted content in 1-2 weeks - we are really busy now :(( -, but sometimes it's just a few days. Users with community area account can add videos also, but this function is limited for invited testers. However we hope this function will be released for the public very soon.
