There you go. Clicking on My Videos will take you to your collection of online videos. You can email the URL to all the people in your Address Book, you can embed the video into a web page and you can share, save and re-watch favorite videos of your own. It's a great big video world.

Aside from rating your videos online and leaving comments about them, your friends and family can subscribe to your videos and receive a notification every time you update your collection. It's all much more convenient than all that nonsense with stamps and envelopes. And since YouTube eagerly accepts video from cellphones and digital cameras, it's relatively easy for even non-skilled moviemakers to join in the fun.

A word of caution: be prudent in your video sharing. It might not be a good idea to be posting online video showing that you're on vacation in the Bahamas, when other videos you've posted show the location and luxurious contents of your home.

Another downside to this program is YouTube automatically picks a frame from the exact center of your piece to represent it - this can make or kill a video. You get two options to change it, made at about the one-third and two-thirds mark, but you don't get much to fiddle with. Who knows, in 20 years there may be a rule of filmmaking that your most amazing, eye-catching scene must come exactly halfway through your movie, and nobody will know why....

So now, get sharing!
