Let me explain one thing about gaming forum - all games dieing at some point. So as their forums. So I don’t want to put forums on dead projects with active forums in one bucket. For example, now I have:
ArcheAge
Recruiting
General Descussion
Our guild
Classes
But when ArcheAge will die, I will have to put this forum in to "Archive" category. With Discourse I can’t do this now. I can only delete all ArcheAge sub-categories and put all post in ArcheAge category, which will create a big mess. So I think there’s gotta be a plugin for more sub-categories, or Discourse devs should reconsider their decision on this.
