3 Ideas to improve the website

I really want viki rakuten to implement the 3 following ideas. To provide speed adjustment for shows and movies. To allow posters to delete their own comments. To provide 2 separate spaces for comments: At the beginning of a show or movie you can select if you are posting and reading as a first time watcher or a repeated fan. This way if people post spoilers they won't ruin the show for the first time viewers.
