How do you get videos on your homepage because one day I was looking at a members homepage and they had videos and I want a video on my homepage. 

Edit Profile => About Me => YouTube Button => Copy Link => Save Changes.

ADK

If for example you wanted a youtube clip on there, go onto youtube, open the clip so its playing on your monitor then copy the url from the top address bar.

Go onto your homepage and into "edit Profile" and just above the text box at the bottom of the page you'll see a small "youtube" icon. Click on that and enter the youtube link in the box that appears.

Please enter text in the text box aswell, the text box won't allow video only.

Save preferences at the bottom of the page, go onto your homepage and press Ctrl and F5 on your keyboard and the video will then appear.
