Thanks a lot for this hack, Kerry Anne! I'm migrating my old, hardcoded sidebar to this system. It's really useful.
However, I'm finding a problem when I try to use it with Logician's webtemplates custom made templates on my website.
The webtamplates powered pages only seem to display correctly when I disable completely the USC plugin. I attach an example for you to see (can't link you to them cause the style is still private).
forumhome.png (screenshot) and forumhome.txt (the source code) are the columns displaying correctly.
webtemplates.png (screenshot) and webtemplates.txt (the source code) show the page broken.
Hope you guys can help me!
