Forum:Help with a Wikia Extension

Hi! On my wiki, I'm planning to insert some sort of javascript code called a Countdown. My problem (not one you would expect) is that my wiki doesn't even have a viable "script file" to put it on. This script file (one that wikia almost always has) is called MediaWiki:Commons.js. I don't think that anyone has ever created one on my wiki. Could someone please either do it for me (if you're capable) or give me a detailed guide on how I may ask for or create one myself? Please, let me know if you can do it yourself and I will give you a link. Thank you! Salience72 (talk) 13:52, September 3, 2012 (UTC)

 * MediaWiki:Common.js always exists. If you haven't created it yourself then it will be using the default code included with MediaWiki (i.e. a comment). Just create a link to MediaWiki:Common.js anywhere on your Wiki, it will show up as a red link, click it and you'll go to the page and be able to edit it (if you have admin rights). The shorter way to do this is just type:  in your browser URL bar. Lunarity 18:29, September 3, 2012 (UTC)

Thanks to all of you! I'm not an admin on my wiki and when I looked up the MediaWiki:Common.js page, I noticed that an admin cancelled it for some reason. Is there any way to bring it back? Do you need a link? My wiki is How to Train Your Dragon Wiki by the way. Salience72 (talk) 02:52, September 4, 2012 (UTC)
