CustomChatStars

CustomChatStars is a simple bit of CSS that allows you to change the chat stars for individual moderators/administrators in chat.

Implementation
Place the following code in either MediaWiki:Chat.css or Special:MyPage/chat.css:


 * Replace "UsernameHere" with the mod/admin's username (replacing spaces with underscores for the rail code) and the urls with a link to the star you want.
