On the subject of category redlinks: The "compromise" kicked in today, and categories started redlinking again. One of the first things I noticed is that (up until recently) not a single category used in the Admin Forum had been created. Furthermore, no one noticed that Admin Forum:Watercooler uses the same category as the now obsolete Forum:Watercooler, thus anyone attempting to view the full list of Admin Forum:Watercooler threads will instead get some absurd number of long-since archived threads. I don't see how Wikia can tell us that this is the best solution when their own staff have clearly made the mistake that redlinks were designed to prevent. Category redlinks are specifically aimed at preventing people from adding categories that aren't part of the system. I think it's clear now that bluelinking categories does exactly what we said it would - it no longer prevents people from adding categories that aren't part of the system.
