Please pardon me if it s a stupid question as I haven t really done a lot of work with categories in the past But does that sort of change really need a CfD I think that if I had found myself with a similar sub cat idea I would have just gone ahead and done it or more likely thrown it at a relevant project talk page to see if there were objections Of course maybe you weren t able to get consensus at the project hence the post to CfD Again sorry if this seems stupid as I branch out into new and different tasks I just like to understand the thinking of people who are engaged with them more regularly I find it helps me with my own decision making
