When you want to add YouTube videos:
1. Place the cursor where you want the YouTube video to appear.
2. Click on the youtube button which is just above the post editing box. It is the last box on the right next to Font colour. Your cursor will appear between these [you****][/you****] tags
3. Go to the YouTube video page and copy everything after the = sign. i.e. https://www.youtube.com/watch?v=rz5TGN7eUcM
4. Come back to your edit box here and paste the snippet between the [you****][/you****] tags.
6. Submit your post or finish writing it then submit it.[Note: **** is used so that these tags do not activate in this post, but it will say youtube]
