reading the copyright definition that indianna posted, I understand that it refers to "works" that has any type of artistic nature or at least some "creativity" basis.
So we all agree it applays to photographs, photostories, dioramas, even customs, etc, etc. All of them with a creativity process.
Now....
information has any creation process??? beside the fact that someone had to type it???
I don't think so. Information is to repeat and to pass what one learnt. So information would not enter in the definition of copyright.
A list of possible new sets IMO is information, therefore, what copyright has to do with it. Information is meant to inform. Information goes mouth to mouth..... as someone said, no one calls the news to ask permittion to tell a friend what they saw on tv.
So maybe next time no one should said that "certain info" was read in "certain forum". Just post it as general info.
"hey I've heard that......bla bla bla."
Problem solved.
