Translates [Itemlinks] posted in chat into your local client's language.
If links fail to translate then its most likely because the games's local database does not have the item/spell in cache yet.
If someone with a german client links something in chat: [Kaputter S.I.E.G.-Knopf]
and you are running the english client then you will see [Broken I.W.I.N. Button] instead.
