you raise good points BR. the main thing I see here is, we don't commonly give out our friends contact info unless we know its okay with them, and this would include internet info (email, board name, etc). And if you do give it out, then you know that person well enough to know they won't mind. if you don't know someone very well, then it's best to ask them first, or just don't give out their info at all. there is rarely good reason to do so. It's just common sense, courtesy, and respect.
my problem with Garner's post (above) is that it only tells part of a complicated story. there is no need in telling it at all.
