Help:System messages

System Messages 

Systems Messages provide a means for customising the look and feel of a wiki. Because their impact is system wide only admins and above normally have access to them. Others may look, but they may not edit.

Appearance

 * Monobook.css - The global stylesheet for your wiki.
 * Monobook.js  - ?
 * Tagline      - Just below the main heading of each page, there is a tagline just under the line. This controls the text of that tagline.

Exif Messages
There are a series of system messages starting with the prefix of exif. These all relate to information pertaining to photographs taken with a Digital Camera. Unless you are familiar with the technical aspects of the exif standard, you are probably better off leaving these particular messages alone. For more information on the exif standard check out the article on Wikipedia.
