Thread:Project:Support desk/How to disable wikisyntax-based parsing of CSS/JS pages?

Hi! I'm using MediaWiki 1.16.1, PHP Version 5.2.14, MySQL 5.1.49-community server. My question is about why are CSS and especially JS pages (usually stored at MediaWiki namespace) by default previewed and rendered as common wikitext? Currently if I want to properly write down some code containing double square brackets or four tildes (for example) I have to escape the whole page with some like // . Maybe somebody knows how to edit certain pages in a raw mode or so. Please give me advice.
