This is just a small preview of the website. The website is functionable and you can make and buy fridge magnets with your pictures. You just have to upload your picture and we'll do the rest. Soon we'll release a full tutorial. Just a test.

You can only link annotations to other URL's within the YouTube site. Off-site links aren't allowed in this feature. To link another YouTube page or video, just click the little chain link thing and paste your URL in the box that comes up. The chain link thing looks a bit like a sideways 8, or oo.

If you want to link offsite, you're going to have to paste the URL's in the video's description. These will hyperlink. You can then put an annotation in your video directing people to look at the description. (less info)
