You're right, you can't embed flash on here. I just posted an image, but I had also posted a link to a website which had the Flash video embedded.
I have no idea any more as to whether Flash abides proxy settings, it never used to, but some are saying other wise now, plus my test failed so I'd be inclined to agree.

True, but I don't have the ability to run PHP/JS/Flash code on here, hence why I had to ship him off to a point I control.
