Ron, I'm sorry if you thought that post was directed at you. It wasn't; I meant it as a general thing. I respect you a great deal, and you've been very helpful to the community. This topic relates back to one of my hot buttons. ^_~ As for if a freebie can be used if the person can't be found, I would suggest anyone who does so contact a lawyer first to see what butt-coverage they need, especially if there's a potential for a great deal of money in their commercial project. There may be legal requirements to make some extra effort to find them, like posting messages on forums or something.
