I thought I'd have a go at sorting out the jumble that is the page categories. There are lots of orphaned categories and some duplicates, plus a few that are probably not needed.
By the way, none of the maintenance reports in the Special Pages seem to work. That doesn't help my cause.
The main reason I'm posting here is because these modpacks and mod names need to be sorted out. For example, is it "Universal Electricity" or "Universal Electricity Pack" (the main page uses both)? You can see in the Modpacks category what I've gone for regarding the modpack names, although the names of the individual mods should be confirmed too.
A little help here before I go any further?
