I'm in no position to dictate what a working pro does with his images. You and all the others are a special case. You might post some throw away shots. Or, partake in the thread as a commentator. My point was to make that thread THE most active thread in the alternative FM forum. Generate traffic, keep it visible, bring in new people.
It can work if done right.
Good luck with your case to claim your rights to your own work!
