Category:Hidden categories
From RRU Knowledge Base
This container category contains hidden categories that have the __HIDDENCAT__ behavior switch added to them, which prevents them from being displayed at the bottom of pages that are included in them, therefore hiding them from readers. Except not really, so what's the point aside from marking maintenance issues? This category is added automatically by the MediaWiki software.
