Hi there new guy! Welcome to TYM, hey to embed youtube vids on here/insert them for instant watching, and not just post the link to click on.
Simply go to the little icon right above your white box here the one that says "Insert Video" click on it and you'll see a little wide box, copy and paste the link from your address bar of the youtube video INTO that and hit ok and bingo! you're done!
That's if you want to show/insert the actual video, hopes this helps! Have fun!
