Bryan,
Did you happen to notice that the link to that thread has been removed? Search for the word "copyright" and you'll see that all discussion of the subject has been removed. So apparently whether someone owns what he creates has become a taboo subject.
I send a polite not directly to the administrator on the theory that the copyright wording was an error - something grabbed from another site and that admin didn't realize what it said, and I received no reply. Heck, I would even have been willing to rewrite it for them if they responded.
Do you really accept the explanation for not being able to mention a competing forum in a post?
If that's okay with you, it okay with me too.
