You don't gift your thoughts to Rich. Ask him.
The phone company doesn't get to use your ideas or the sound of your voice. An idea you speak about in a letter to the editor does not become the newspaper's to use.
TFL is a media, and owns the server space, and they can delete what they want from it. But they cannot use your ideas or language for profit without your approval.
Oleg Volk understood this when I asked him to delete some design ideas from his website.
If you post on this board or any others, if you use their software to show your pictures, then the things on their boards belong to them. You have presented it in a public forum and belongs to the owner. Unless you have some sort of "this is copyrighted" remark which the board owner can just delete it from the board and therefore, it is gone.
The phone companies use your ideas all the time. If you call them up with a good idea, and they use it, and you didn't pay the copyright, then it is their's to use.
And yes, if you send a letter to the editor, they can do anything with it, print it, use it, whatever. They do it all the time in the "letters to the editor" pages. If you subment the letter or idea you are giving them permission to use it. Now if you put a disclaimer in it like "cannot be printed, used, etc.. without my permission" then they will do like Rich would do, delete it.
Actually, if you bothered to read the rules and FAQ of the board, Rich (and others) hold the right to use what is posted or said . When you hit the "I agree" button, you just released all ownership of what you say or post (to clarify: On the board).
Oleg may have, or may have not, I don't know the background on this issue so I can't really comment. If his personal website then maybe he misunderstood what you were doing when you gave him the ideas and looked into it. If THR then he is not under any obligation to do so since now they are public knowledge and he holds the rights to what is on his board.
Bottom line is this Handy, if you don't want others to use your ideas to make money, which aren't copyrighted, then don't post them. Or, if you post them, make a disclaimer and be done with it.
