It works for me.
1. Go to you tube.
2. Pick a video.
3. Highlight the url of that video and select copy.
4. Come here and select reply with quote.
5. Here's the kicker, go across the top.
It starts with A/A and moves across to the end.
The very last icon with color to it is to insert a video.
It's the next to last icon there is.
6. Click that icon
7. There is a bar across the top of it to put your url video in.
8. Select that rectangular box, right click it and then paste.
9. Then click okay.
10. Your video should show up and then click post quick reply.
Before you know it, you be bragging to all the new people how simple it is.
