[Mediawiki-l] disable skins changing? --- remove it from User Peferences?

[Roger Chrisman]

Hi,

I want to remove the item from the User Preferences page that lets Users 
change the skin they see my site with. What is the best way to do this?

*Why*
I want to remove the skin choice from User Preferences because I have 
some customizations in Monobook that are important to my site and I 
don't want to go though customizing more than one skin.

One example of my site CSS customizations is some green bordered cards 
on a page. The cards' green borders and layouts are CSS classes 
customized in
  skins/monobook/main.css
and, so that they will print properly, also in
  skins/common/commonPrint.css

The green bordered cards are on this page:
  http://wikigogy.org/Discussion_card


Ideas?

Thanks,

Roger :-)
