I'ma have to ask you to stop adding the month before the year on book article introductions. For years we've only just listed the year, so I don't see the point in changing it now.
Also, what was up with that edit you made to the original series page back in October? You changed all the colors to match the books' exact spine colors, which made some of them hard to read, plus all those bright colors really don't look good against the wiki's black background. It just looks unprofessional.
I mean, there's hundreds of book pages that list only the year in the intro, so I think adding the month to it now would be too much work. Don't think it's really worth it. And I don't want some pages to list the month and year while others list only the year, I want consistency.
The episodes category is already covered well by One-Part Episodes and Two-Part Episodes and Episodes is apparently a candidate for delete anyway, so I personally don't think it's wise to go adding it to all of them.
Or... Well... Maybe they should be? It seems like the year-categories are very inconsistent in regards to what they're tagged with. I'm not exactly sure what to do.
I'm going to maintain that the year-categories shouldn't be tagged by the series within them. One of the wiki rules is, "Don't tag lists pages with information regarding individual books featured in that list." I think this also applies here.
