Special:Badtitle/NS90:Category talk:Σελίδες στα Ελληνικά/el/Duplicate categories

I created this page according to what is written here: http://userbase.kde.org/Category_Translations_Greek_Esperanto_Spanish. Afterwards, I found out that category: Σελίδες στα Ελληνικά already exists. Thus, we have two identical categories. I think that one of them (probably this one???) should be deleted, right?
