I'm using the latest atahualpa-build. I use the 2 Sidebars (Right sidebar + Right Inner sidebar) and the central column of the topic.
Now I want a third one above those two, one that spans both of them. I don't want the third one to be above the header or something like that, it should still be a sidebar.
Could anyone please let me know how to do this.
It'll be really very helpful.
