I'd like to add an iframe in my sig, where when the user visually reach it when scrolling, it automatically will redirect the user to a website of my choice. Would be this possible?
Edit 2: Jokes apart, I think that it will be a cool core extension where you can set a value for the max. width or height of them. Also, yeah, the option to completely disable them all on the forums, per user basis, would be a required one in my humble opinion. Great work guys, as always! Can't wait to see them live!
