Welcome aboard. Nice post. Good luck. Fight the Power.

Welcome! I highly recommend you start with Videosift's FAQs, as most of your questions can be answered there.

http://www.videosift.com/faq-en.php

The thing about videosift is that it is difficult to get your own personal videos onto the site unless you persuade some other sifter to post them for you - the concept of "no self-linking" (not posting videos you made or have on your own YouTube or similar account) prevents Videosift from becoming inundated with people self-linking to themselves and artificially increasing their own stats, as well as preventing nonsensical home movies from flooding the site.

The rating system is other VideoSift members voting (up or down) on your video. You need 10 votes on a video to get it published to the front page, otherwise it sits in the "Unsifted" pile and if it runs out of time there and it will go into your "Personal Queue."

Hopefully that answers some of your questions... if you have any more I'd be happy to try and help you out.

In reply to this comment by Hooghoudt:
Hi, I'm kind of new in this site. Where can I find tips on how and were to post nice video's and about the rating? I have a few more nice classical/rock video's I would like to share and get commented on.
Your reply will be highly appreciated.

Rgds,
Peter
