Plurals in category names
Thanks for working on category maintenance.
I am leaning towards the plural form of categories as well. In addition it should not be that much work to recategorize using a bot. I currently have two bot accounts User:KruhlyBot and User:KruhlypyBot (different interfaces) that could be useful once things get rolling.
The bot is a really good idea, but I don't think it's so much of a task I wouldn't do it myself. It is probably something I could do during the actual process of restructuring, and having a bot do it may just make extra work (since I'd already be looking so closely, and the bot's work needs to be checked anyway).
