User will get the same result if "Full Screen applet" link was clicked.

Do you mean: instead of showing applet as part of forum message, only display "click to run" button to wait for user action, then display applet in a popup window?

My suggestion is 2 options/ways to embed applets
One is the usual iframe which just implemented
The other is a picture after click is a pop up window of the full screen applet. Check out the Phet simulations like the image above the second option
Thanks !
