That does seem to shed some light on the subject. Basically, the "object" I mention above is the shorthand way of creating an object/function and it's a Singleton. There can be multiple instances of the "class" above. I suppose if I don't need the extra functionality that the (Mootools) class provides and I only need 1 instance, I can just create an object.

Thank you!
