Lots of times here, and on thousands of other hobby forums on the 'net,
photos or other material that has been copyrighted at one time or another,
are posted for non commercial hobby reference purposes,
without proper reference or permission.
Now lets get one thing straight.
We are not talking pictures clearly marked with a watermark copyright,
or those that the creator marked with their name or company name.
They are clearly off limits UNLESS YOU HAVE THAT PERSONS PERMISSION to use them.
This should be noted when you Post.
Photos that you have grabbed off the 'net, that are not credited where you found them.
MARK THESE "FROM NET"
Photos that you have collected over the years,
and have no idea anymore where they came from.
MARK THESE "FROM MY COLLECTION"
Photos & text from a book is the authors work, and is rightfully their property.
I respect this (and so should you).
So if you Post any of this, get the authors permission to us it !!
Then mark this "FROM [BOOK NAME] WITH AUTHORS PERMISSION"
