When I read Jim's comments, I could feel the pain and discomfort he was feeling. I do feel that people should think about what they're doing before they post. Not excepting myself from this - I'm sure that all of us have overstepped the bounds of common courtesy, etc. at various times.
I think that all of us should remember that we are guests here and should try to act accordingly.
Maybe this makes me sound like a stuffed shirt, but it's what I feel is right.
