Geezer here: Welcome aboard, Lee. You'll find lots of good info here, and best of all, everybody is friendly and supportive. Sarcastic jerks... there have only be a couple, and they either straightened up or took a hike. So don't be afraid you'll look stupid. All of us do that occasionally, but the friendly spirit hereabouts makes learning a joy.
I predict your biggest problem will be deciding what to build first... there's just So Much here. Geezer.
