Block, believe me, I didn't think I knew it all after the Monkinar. After the reaction to my posts here, I initially was reluctant to expose my ignorance in the future. On further reflection, I'm glad I posted (and will continue to do so frequently) because I learned some things which I wouldn't have otherwise, and indeed I was holding some incomplete if not mistaken concepts. I see the Monkinar as a very good start, but the posting and reading of the boards is like continuing education for me. One thing I do know is that I seek out advice and knowledge from those more experienced, but still question them at times. Ass a final comment, I didn't crash the computer, it crashed me, but I even learned from that.
