I have three short 'historic' videos that I'm trying to add for classmates to view;

What I'm actually trying to do is to put this info and the links and video on our site, linking to YT as needed to let classmates know of this service - I'd like it and the links to be in the Message Forum, with a link to the Message Forum posted on the Home page, with links to the YT videos actually in the message Forum...NOT on my personal page strewn in with everything else. Thanks

I'm assuming you do not want the video to directly be displayed anywhere and only end up on the YouTube page.

This is a LINK-TO-YOUTUBE-VIDEO

If that's what you mean that uses the normal hyperlink option.

To get to the Message Forum, you make a link to the message forum containing that link Topic. You can't link to anything within the topic that I know about.

So each video link would need a separate TOPIC within the forum.

You could put the actual video as the topic too using the embed option. JVideoPlayer would let you combine ALL the videos into a list one could pick from if you actually wanted to see the video. One can still go to Youtube from there too.
