Whenever you write something, you own the copyright to it such -- even these posts are the IP of the individual poster and they own the copyright to the contents. Yahoo does not own it, the group owner does not own it and in the Yahoo TOS, this is so stated.
In another group that suffers from overt estrogen overloaded, 1 person wrote a guide, lifted whole posts of other members and put them in her guide (without credit or permission) that she sold and was called on it. The person who was charging for the information had to refund money and revise her guide to be strictly and exclusively her own words. That is an example of copyright violation.
I use and quote George C Lane and his application of the stochastic formula all the time and it is NOT a violation of copyright because the settings are mine that I have played around with, I give credit where I have learned something from someone else such as David Elliott about stochastics settings, etc., and don't lift entire paragraphs or words in the same series as their works. These are not copyright violations. These come under the fair and free use concept.
If I am discussing something from a trading book or manual that is copyrighted and put it into my own words even though it is not my original idea, that is not a violation of copyright.
If I write a book or prepare a PP presentation and pass the work off as my own when it is based on someone else's work and the charts are THEIRS I lifted entirely, word for word or exactly the same indicator settings, other than my own stochastic settings I've developed, and sell it, that is a violation of copyright.
The two elements are: passing stuff off as your own when you copied it from someone else and selling it as your own idea.

No. It appears there is a lot of confusion on copyright laws. A good
discussion is at http://en.wikipedia .org/wiki/ Copyrights. OF course
this isn't official but it is an easier read than the law books.
People like Wilder published his works so others could benefit from
his discoveries. What the copyright laws do is prevent someone from
copying his work and selling it. But the intellectual property he
disclosed is for our use. Why else would he publish it?
