Looks like new sections are added by adding them to Categorized Q&A Sections.

It seems like this is broken. I havent the foggiest how it works actually so im not sure how its broken. I fiddled with it on test one time, but its broken there too. And actually something that I did a while back with theorbtwo broke the test server even more (we changed the indexes and the primary key to prevent duplicates in the same nodegroup. But foolishly I didnt by the orderby or rank field in the index. Actually i havent figured out why we have both.)

Anyways, as ill say in a repy to the root of this thread, the new section is added. :-)
