I had started a notepad file that contains a lot of good info like you talk of. Here is a copy & paste of it. I'll try to go back later and clean it up a bit. If you see something that is incorrect please let me know. Also, If I quote you and do not put you as the source, I'm sorry, Let me know and I'll fix that. I am not trying to "steal" your work. Some of this info may be opinion based. I basically grabbed it from threads and made a little cheat sheet for myself.
