Cool. But don't make the mistake of thinking that's all there is too it. You've just made the first step. It's a looong journey. There's a LOT more to understand. Buckle up and prepare yourself. For a lot of us, it's great to find an "explanation" but a whole other thing to wrap your head around all the implications. Lot's of ups, downs, bumps and potholes ahead, so get ready. It could be a rough ride, but it's worth it.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
