Construct 2 -> HTML code

Is there any way I can convert a construct 2 project and embed it into a forum. I know and read up upon several in which you had to be an admin, but is there any way for a normal user to without having any access to adminstration panel. The forum I am referring to is Vbulletin Version 5.1.1

Export to HTML5 like normal, host that publically, then iframe it into the forum maybe?

I have read up on iframe. It doesn't support iframe

According to this it can: http://www.vbulletin.org/forum/showthread.php?t=170132

But if the forum you're on won't let you, then I don't think it's possible to embed it :/

Thanks. I'm asking them if iframe is supported right now. Do you have any ideas of putting a countdown timer on a post just being a normal user? :O

Most forums don't allow you to embed arbitrary HTML for security reasons, so I doubt this is possible.
