Forumer

You can embed videos. I have before on my site. You must do the following:

Make sure you forum allows HTML.

Then check the HTML Tags in your configuration page under General Admin in the Admin CP.

Under Allowed Tags I have: This allows you to "embed objects" and also allows you to use Flash on your forums which I was told you never could do.

Once you make the above adjustments, all you have to do is copy the embed link on YouTube and you video will display in your post.

Here is an example of a You Tube Embed link:

Notice the HTML codes <embed>, <param>, & <Object>. If you don't allow those tags on your forums, you will not be able to use them, thus making the Youtube video unavailable.

For the video/HTML to display in posts you (and every user) must also allow HTML in your (their) profile.

Each user has to enable it for them selfs so they can see it, if another user doesn't do it that will not affect your ability to see the HTML if you allow it for yourself.

Guests can not view html, they will only see the code until they register/log in and allow it in their profiles.
