Using YouTube is much more intuitive than I ever thought. As long as you have a login account (which is very easy to make), you can upload videos easily from your machine)

1. Go to Youtube.com
2. Login
3. Choose Upload video
4. Fill in all the fields – screenshot –>
5. Click Upload video
6. Browse, find your video, and click upload video
7. It may take a while, but be patient
8. Take note of the url for your movie, and share with friends!
