By looking on XD1's edit, it seems you need to add to your MediaWiki:Common.js: /* Snow */ importScriptPage('MediaWiki:Snow.js'); And create a page called MediaWiki:Snow.js. Paste there the content from the same page in the community central.

Though it seems the code is copyrighted, so make sure to paste the section from the top of the page MediaWiki:Snow.js as well, which gives information about the copyright holder.
