You can use this thread to practice as many times as you need and feel free to ask any of the heads or moderators for help.
For Mods/Administrators you can do it this way if you like:
There's a control panel at the top of the page that says:
"General Control Addition Users Design Multimedia Help" (at least that is how it is on mine)
click on "Multimedia" and go down to "Insert Video (youTube...)"
it will say "Address of page or Flash-file:" with a bar underneath.
in that bar, put the address.
wait for it, click away, w/e. the other bars will fill automatically.
when they do, take the BB code (second bar) and simply copy it to your comment.
