I am already running the Beta 7 on my site, if any bugs, could it be fixed without affecting user posts and information? and how can I add ads like google adwords and ansense? waiting...

There is an adsense custom block over at UBBDev:

Thanks Gizmo! gonna get it right away!

Hey Gimzo, how do I insert heading banner ( just like the one here: http://www.ubbdev.com/forums/ubbthreads.php/ubb/showflat/Number/311187/page/1#Post311187

and how do I change the background color?

That block at this time is just for insertion as one of the sidebars or in the post header area; I don't know how to set a block to be in the header or footer areas (yet)
