I'd like to request the installation of this extension on our site. I am aware of the message we are required to implement and I have done so on our rules page.
https://www.mediawiki.org/wiki/Extension:AccessControl#Installation
In conjunction with this, four groups need to be set up:
UserGroup|CustomNameSpaceItCanRead
Player|Player
Contributor|Contributor, Player
GameMaster|GameMaster, Contributor, Player
Administrator|Administrator, GameMaster, Contributor, Player
I hope this is the correct way to ask for the installation of this extension. Please get back to me should I have gotten anything wrong or expressed myself poorly.
