I'm Madness, and I'm here to show the new Wiki Extension, known as Gadgets! This extension allows you to enable scripts and other CSS and JS. For those of you who don't know what I'm talking about, just go to My Preferences, then the tab gadgets. There will be a list of certain scripts that you can enable within the click of a button, rather than adding all the code to your wikia.js/css.
Okay, so far Users who don't know what all this is this: Custom css, and js, can be used to modify how the Wiki looks, and add functionality to to editing, or the Userpages, etc. An example would be the Quick Images License Script. NOTE:You do NOT need to know any JS, CSS, or any code. The reason this was made was for Users who have little to no experience with code, or anything of the sort.
That's all I have to say, so I hope this helps. Take note, there will be more gadgets added everyday for the next week or so.
