I apologize for only having read Micca's initial message, and please mind that nothing of what I want to say relates to any of the answers. I don't know them as I write this.
Micca - this is a PUBLIC forum, something like TV. EVERYBODY can read what you are saying (just look at me). You needn't tell your name or show your face, but whatever you say can be heard by everybody who is only interested. There is no privacy here. (And if QE2 reads this message nothing can keep her from doing so and still nothing can keep her from flaming me here in public for having called her QE2 without any possibility for me to find out who she really is.)
That means that if you want to post something that should not be freely distributed you should at least be fair enough to tell this by adding a copyright notice AND you must rely on the fairness of EVERYBODY ELSE to also copy the copyright notice when freely distributing what you published.
So to me it is much more an ethical question what I post here than what I do with things posted here. OF COURSE I copy things and I print them and I give them to people I think to be able to appreciate them. Don't complain - it's all 'public domain' unless otherwise stated.
On the other hand I am VERY careful when posting information referring to people I know (including myself). They might be identified by themselves or - still worse - by people who know them. And then I'll be in trouble. Publishing (and this is done here) personal information of any kind is something to be thoroughly considered - for ethical reasons. If one wants to discuss things that really matter they can never completely avoid talking about personal things (is that "one...they" correct in english?). So - as you can't use the 'DO NOT', try to apply the 'THINK ABOUT' as well as ever possible.
(PS: There might be people who are concerned about me still posting as a guest, but I know what I'm doing - it's also related to questions like this one.)
