I speak to Cathy on a regular basis (she was at my house last night) and she is doing well.
I do know that she did get frustrated with some stuff on the board. I will not try to speak for her on this, however I myself have noticed that there are some folks who tend to take the help and advice given here as though the giver has some obligation to do so. That including criticizing the help given, not acknowledging that the help was given, or even things like the above comment about being called a know-it-all for trying to help.
Cathy really DOES know a hell of a lot, and even more important, SHE is willing to admit when she does not know something and is willing to admit when she was wrong, which some folks are NOT so good at....
