Insert a webpage into my sig?

[4g3nt_Smith]

Suppose I wanted to add an html page into my sig, maybe http://www.ag3nts.info/nowplaying/RecentlyPlayed.html ? How the hell do I do this, and will it work in any way without the use of html tags in my sig (for say, a UBB that doens't allow html in a sig?)

ok. Anyway, I found out its done with an iframe, so my question is answered. And who ever said I would remove my current sig?
