In this page https://smn.wikipedia.org/wiki/Wikipedia:Mii_lii_kooveest I have made an inputbox for adding new sections to the page. While it seemed to work for a while, it has now started producing pages in the main namespace instead.
Let me know if I have missed some code error, or if there is another kind of problem.
I am also using Discussion Tools on the page. There are still some placeholders for the reply links, just to clarify.
