I would like to create a new widget area in my right sidebar. I would want it to be the width of my right and right inner sidebars together with the right and right inner sidebars immediately below. Is this possible?

yes and there is an explanation in the Gold Forum Tutorials - HOWTO: put an AD (or other) widget over/in the middle/under two sidebars

the gold forum is available to members who have donate $20 or more.

Ok, I made the donation. Do I just have to sift through the Gold Forum Threads or is there any way to have the link sent to me?

Nevermind. Not much "sifting" to it when you click the link for tutorials. Thanks!
