Please quit posting blind YouTube links. No one likes to click a link without at least getting a small preview at what the video is about from having it display in the thread.
In order to do that, this is how you would go about posting your YOUTUBE video.
First off, you can do it the Fast Way or the Manual Way (your choice).
MANUAL WAY:
1) Find the link you want to share from YouTube.
This is usually found by clicking the SHARE button under the video.
It will then bring up the link.
COPY ONLY the funky letters & numbers at the end of the link (as you don't need all that other garbage.)
example of what NOT to highlight (in italics):
https://www.youtube.com/watch?v=DcmzHtokiMw (<---this whole link is not necessary)
example of what you SHOULD highlight (in red and italics):
https://www.youtube.com/watch?v=DcmzHtokiMw (<---only the part in red is what you need)
2) In your reply post you are composing, PASTE the code you copied.
3) You can then ADD "youtube" brackets in the front and end of your code. The end bracket will have "/youtube" and the front will not have the SLASH. The brackets are the SQUARE looking ones as such: [ ] Put one set around each youtube and /youtube you add.
4) Click PREVIEW POST to make sure it's displaying correctly. If not, fix what you think might be wrong. If still not working, then use FAST WAY directions.
5) Manual way is best for using QUICK REPLY if adding to an existing thread. In order to get all the HTML options, you need to click REPLY button. If REPLY button on the right next to QUOTE is not taking you to the reply area, then try the REPLY button on the left under your avatar.
FAST WAY:
1) Find the link you want to share from YouTube.
This is usually found by clicking the SHARE button under the video.
It will then bring up the link.
COPY ONLY the funky letters & numbers at the end of the link (as you don't need all that other garbage.)

example of what you SHOULD highlight (in red and italics):
https://www.youtube.com/watch?v=DcmzHtokiMw (<---only the part in red is what you need)
2) Click this ICON found 2nd from the end of your HTML choices line. The HTML choices are the ones above this composition box....that start with B for BOLD, I for Italics, etc.
3) PASTE the code you copied between the brackets.
4) Hit PREVIEW POST to doublecheck...and if correct, then hit SUBMIT.
The fast way doesn't look any faster?
Well once you know what to save, this is how fast it looks:
CLIFF NOTES FOR FAST WAY:
1) COPY code from link
2) Click
3) ADD code btwn brackets
4) Hit SUBMIT
What would YOU rather click on?
A blind link like this:
https://www.youtube.com/watch?v=DcmzHtokiMw
Or a video with a preview like such:
(I thought so...)
p.s. For High Definition preview, use the button to the RIGHT of the regular youtube button
NOTE: HD might not be available for all videos on YouTube.
This is the same video in HD:
