Video embedding tutorial

This is a good explanation of how to post Youtube videos (it also works for other video sources).

This is also probably a good time to talk about uploading videos to Youtube. Its free. You just need to create an account. They are associated with (or owned by) google, so your gmail account may work best here.

Once you set up an account, uploading video is pretty easy. They accept most file formats, though there are limitations on size (no bigger than 100mb, no longer than 10 minutes? i'm guessing). And there's plenty of help pages.
