I had taken a long break, came back and EQ alone had a lot of changes, the walk throughs are nice, not everything is answered, but it's enough to be dangerous LOL... that said, I definitely found that learning and refining the INI taught me the most; experiment here, ask a question here, apply it there, seemed to teach me the most about it... I really enjoyed the older INI websites that walked me through (though I believe some are out of date or whatnot... they still were a really great place to learn a basic knowledge)
