The article Cooba linked to is actually slightly inferior to the one Violet has on JCSref (See Modifying your newly understood MCE under GENERATOR). I still don't see the purpose of having both the JCS article section on J2O and the JCSref website. If you ask me, instead of JCS articles on J2O, there should just be a link to JCSref where anyone with J2O membership can post an article (or I should say "a tutorial" since it's a little more than an article). But... that's probably asking for too much.
