I added [b]Embed[/b] button for each message.
User can click the button and it will display html code to show that message inside a single iframe.

probably not unnecessary

I also added an [b]Embed [/b] button for uploaded EJS simulation.
User can click the button and it will display html code to show that applet only.

do you have this too :)
[code]<div style="position: relative; width: 300px; height: 200px;"><a href="http://phet.colorado.edu/sims/pendulum-lab/pendulum-lab_en.html" style="text-decoration: none;" rel="external"><img src="http://phet.colorado.edu/sims/pendulum-lab/pendulum-lab-screenshot.png" alt="Pendulum Lab" style="border: none;" width="300" height="200"/><div style="position: absolute; width: 200px; height: 80px; left: 50px; top: 60px; background-color: #FFF; opacity: 0.6; filter: alpha(opacity = 60);"></div><table style="position: absolute; width: 200px; height: 80px; left: 50px; top: 60px;"><tr><td style="text-align: center; color: #000; font-size: 24px; font-family: Arial,sans-serif;">Click to Run</td></tr></table></a></div>[/code]
this rationale for this is in low bandwidth cases, only the picture is loaded, if "click on to run" applet to load the  full screen version for example http://www.phy.ntnu.edu.tw/ntnujava/htmltag.php?code=users.br.ahmed.users_ntnu_fkh_pendulumperiodangle_pkg.users_ntnu_fkh_pendulumperiodangleApplet.class&name=users_ntnu_fkh_pendulumperiodangle&muid=37048 . U recently added the full screen applet which is super awesome!.
for your consideration :)
