One of the strengths of a wiki is the possibility to use several categories for the same entry. I suggest that this index is categorized both as DCU Group and Superman Group as they both hold true. The Superman Group title indexes are a subset of the DCU Group. But it can still have it's own page, that is a great service to the readers. This is how we did something similar with categories for Swedish Seriewikin: http://seriewikin.serieframjandet.se/index.php?title=Kategori:Serier&from=Captain+Marvel+(Marvel) --Daha6439 22:10, 25 August 2010 (UTC)

Check the Category:Series_Group_-_DCU page. I've made the Superman and Batman series groups subcategories of the DCU series group. On top of this we can make a big DC Comics category that will list ALL DC title indexes in a big complete listing for those that don't want to have it devided into groups. --Tenzel Kim 22:39, 25 August 2010 (UTC)
