Thanks. The best site I've come across thus far is howstuffworks.com.
It's pretty good at explaining things without making them too technical. And the diagrams are helpful.
As for this site not helping any, it's what I've been told, but I suppose if I ever come across a question that I can't find the answer to online or something that is only described in technical terms and I needed it dumbed down, that's when I'll come asking for help.
