That was me LionHeart, welcome to our forum.

And sad to say, I'm a user rather than a maker, so I can't answer your question. Taz and the Plastic Squirrel are the ones who would know, but probably won't be able to provide you with more info than the name of a book or the URL of an applicable website, if at all, due to time restraints.

Meanwhile enjoy this, "The one site to rule them all."
