Embedding video
The easiest way to insert video so it shows up in the post window (instead of just a link), is to copy the object tag from youtube or wherever and paste in into the 'Source' view when editing.
For example, the G&L factory tour video on youtube is at this URL: http://www.youtube.com/watch?v=XViK4l...
This is a link to the entire youtube page with all the stuff surrounding the video. If you look on the right side of that page you see textbox called "Embed". Copy the entire contents of that textbox to the clipboard. It should look something like this:
<object width="425" height="344"><param name="movie" value="someurl"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="someurl" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>
(note: you can also get to this information in most embeded videos by clicking the up arrow thingy in lower right of the video)
Then come back to the editor here, switch to source by clicking the 'Source' toggle button above the editor on the left. Paste the object tag into the source window. If you are unfamiliar with html, paste it at the end. Toggle back to the normal view by clicking the 'Source' button again. You should see an outline square that says "object" in it. You can move, copy, paste or resize it in this window.
When you submit the post you should see the actual video in the square.
If you have trouble with this, let me know. I modified the forum software to enable this. I do not know if it will work with all video sources.
