This is one thing I was looking for. Try it and comment

I activated this plugin. Can it be used on the wire? Because it is not working on mine... I really want it to be used for the wire as well :)

This plugin doesn't affect the wire, only comments.  The wire isn't comments.  You'll either have to extend this to cover the wire or write a new plugin.

what would the steps be to rename the wire? I am kinda new at this, you could message me so we dont fill up this plugin space.

@Biddum - renaming something is one of the easiest things to do in Elgg.  See the docs: http://docs.elgg.org/wiki/Engine/Internationalisation#Internationalisation

so with this is can change thewire name, activity name, file name, etc ?

pretty much anything, my rename_* plugins are simply dynamically creating language strings
