I know I'm not a mod and probably have no right to post this . But I noticed a lot of people have trouble embedding youtube vids.
When you click the Youtube button, you should get the brackets [ YOUTUBE ][ /YOUTUBE ]. You want to take the portion of the URL with JUST the mishmash of numbers and letters after the equal sign and insert it between the youtube brackets. Don't use the whole URL.
It should look something like this [ YOUTUBE ] N6FCuTCLNq4 [ /YOUTUBE ]. Minus the spaces of course.
And you get a video of Pronto too . If you quote me, in the reply box, you can see exactly how I did it too.
