Thread:User talk:Metalhead64/Help for namespace

Hello. I'm contributor (since 2011) and administrator (recently) in Mongolian Wikipedia. In Mongolian Wikipedia should change some Namespace name in headline bar. Especially "Category". But i can't discover editing source. How can suit this.

In my opinion〈Category:〉 namespace — should not 〈Ангилал:〉, but should 〈Анги:〉. Example: 〈Ангилал:Франц〉 → 〈Анги:Франц〉
