When you have a forum with a lot of categories that don't get much traffic, do you ever just hide them from use instead of removing them from your site? I used to just block off topic areas when no one would post to them. I found having too many categories can cause issues. How many topic areas have you hidden or just removed? I keep them active but hidden so I can go back and read old posts if needed. I was thinking of just adding them all to an archive section like some forums do, I might just do that.
