If your Ning.com website allows members to upload videos, you can grab those videos and display them in your own webpage or blog by using the embed code. Here's how:
Video tab. Click on the Video tab to see what videos are available at the Ning. Here are the videos at the Aesopus Ning, for example.
Click on the video you want to use. Below the video, you will see a link that says Embed Code; click on that link.
Copy the HTML Embed Code, and insert it into your webpage or wiki or blog - wherever embedding is allowed... like here at Blogger.com! To make it fit, I changed the width to 400 and the height to 301.
