would be good to see you as well.
Here's how to embed youtube videos.
right click on the video and select "copy embed code"
then come back here and paste that code in your OP, or your reply. Then you'll see a grey button Jon made that says "Make embeds load faster" just above the box you're writing text in. Click that button and it will revise that block of code. Then submit and you should be all good.
