How do you put a Youtube video here?
Use these [noparse][YOUTUBE]youtube tags.[/YOUTUBE][/noparse] For the video, make sure you only have the number and letter part. For example, in this video http://www.youtube.com/watch?v=TnQzG2CXngI you only put TnQzG2CXngI in between the tags. The finished result should look like this (without the spoiler):
