ah, ok. So it either a forum, or a subforum of this forum, but not the forum including all its subforums. That is a pitty. I do not use categories, but around 10 forums and each of them has several subforums, sometimes also sub-subforums. So my users will not like the idea to click like 20x on different what new items, just to be able to see the one forum with its subforums.
Would it be technically possible to modify this addon to use several node ids for one single whats new point? If yes, could we collect money t get this done? I really need this functionality badly.
