I am really glad you like the tutorials, and that they are helpful and informative. Some of you probably know I was really still bumbling along on most of this stuff until many fine people helped me see the light on some of these same issues. I'm terrible with names, but Lourdes was one of those people who provided encouragement and englightenment. Doug Sturk, Senjin/Paradox, Violetau(!?) are amongst the others.
