[edit] Overview

This is a modified version of Extension:SpecialInterwiki by Stephanie Amanda Stevens. It adds the following features:

  • Interwiki URLs are shown as links, so you can quickly check validity (and answer the inevitable "what the heck is that wiki?" question more easily)
  • Compatible with MediaWiki 1.14 (there was a class name conflict)
  • Version data has link to this page (original extension had no URL)
  • Description changed to shorter "Interwiki alias management", so it will be where you expect it in the list (under "I" instead of under "V")
