Well, after almost a month, I repeat:

- The tags do not work, that is, if I add a tag to a video, this is not added to the list of tags. If the search engine and put a tag search in videos, can not find it, if not find the name of the video.

- You can not send messages to members. Only friends. And the output tray does not work.

I had to wait almost a month to a response from the admin.
