From the pull request noted: This page lists the current Help:JavaScript review process review status of MediaWiki namespace scripts on this community. Note: you can add and remove local and dev.wikia.com script imports without the review process via MediaWiki:ImportJS. Here, you can easily import scripts: Names should not contain the MediaWiki namespace prefix. Write each script on a new line. See Help:Including additional CSS and JS for more information. Then farther down  Information for user how to add scripts. For scripts from local wikia, user should only add article name and from dev.wikia.com should preceded them by "dev:". Also user should add MediaWiki namespace and should add each script in separate line. There's a typo. The first quote appears to be correct, because the php script splits the title at ":" and counts the parts. If there's 1 part (i.e., no ":"), it pulls the file from the local MediaWiki. It there's 2 parts, it pulls it from the dev: mainspace.
 * from your local wikia by article name - e.g. MyScript.js
 * from dev.wikia.com by article name, preceded by "dev:" - e.g. dev:Code.js
