The guide to embed youtube videos in a post !
1. Click the flash button on your bottom right over the smileys.
2. Paste Youtube link into the link box, here is the trick. it is guaranteed to work with the shortened url, that you find in the share button beneath the video. it should look something like this ex. "http://youtu.be/WuiQOhNpJeE".
It is not guaranteed to work properly with the regular url you can try it, but it did not work for me.
3. Preview the post before you post it to make sure the video is there.
There you go.. no so hard was it.
