IA Donna--I've stayed away from this thread for obvious reasons, but I don't entirely disagree w/Carol Jane. I don't know if swearing here can or should be prevented, & I do believe certain swear words are worse than others, but I also think that no matter how angry someone is or how strongly they'd like a point to come across, it can be insensitive to use the more extreme words.
I'm no prude & I've been known to put truck drivers to shame w/my language, but I try to be considerate of others who find it offensive. The problem w/cyber chatting is sometimes things come across differently when you write them as opposed to how you'd say them, and you don't know your audience or their reactions very well. So it's better to err on the safe side & just use curses in private messaging. ;-)
