WallGreetingButton

This script adds a button to Message Wall pages that allows users to easily edit their Wall Greeting.

This tool is both a convenience, and provides a means for less skilled users to access the feature.

Installation
Add an import line to your  if you already have one, or paste the following the code into MediaWiki:Common.js:

Operational Notes
Wall Greetings, for a completely unclear reason, can only be viewed by the user who owns it, and the wiki sysops. As such, the wall greeting button will only appear on each user's own page. The only exceptions are administrators who will see the button on everyone's pages.
