I have added a function to the forum for embedding youtube videos into postings. When you view a video through the youtube web site you have the option to copy the link for it or you can copy the code to "embed" the video into your own web site. I have posted an example below from a documentary about 2012. All you do is highlight and copy the embed script from the youtube page then when posting on the forum click the youtube button at the top right of the message box. Then past the embed script between the two tags that will now appear in your message box.
I hope this will prove to be of some use to visitors to the forum
