iFrame Auto-scroll to bottom of the page

[ßodo]

I have an ajax chat integrated into my index page of the forum thorugh an iframe. It loads great, and I removed the scrollbar. I wrote a script to allow scrolling by hovering which also works. Now I want the iframe to load the document from the bottom instead of the top. I looked all over for hours and tryed at least 10 different codes, but it doesnt work, any help?????
