Sure thing, KMA. Jews believe that you should not write out the true name of G-d, though most people utilize this tradition only when writing in hebrew. I don't follow this convention in English, except in this post as it felt appropriate.
So Jews call G-d all sorts of names, like Elohim and Adonai and several other names rather than actually write out his true name.
By the way, I've edited my post you are responding to - I think I totally misunderstood what willravel was doing, and if so then obviously my riteous indignation for the night was misplaced.
This is a good website to explain it.
