Quick Answer
Make custom plugin functions chainable by always returning this (or this.each()). In the plugin: return this.each(function() { $(this).doSomething(); }). This returns the jQuery object, so users can: $(".el").myPlugin().addClass("active").fadeIn(). Returning anything other than this breaks the chain. This is the most important jQuery plugin contract.
