To all concerned. I'm temporarily locking this thread pending discussions. For the time being the disputed material will be removed. Please discuss any further copyright issues regarding the material in this thread
in this thread instead. Thank you for your understanding.
We'll return things to normal as soon as I have clarity and have conferred with Ferrix. Ultimately the risk of carrying disputed material on this site is his.
ETA: There doesn't seem to be validity to the copyright claims. Further discussion regarding the copyright issue should be in the above-referenced thread.
I'm unlocking this thread to permit further discussion of the implications of the letter Prosper issued. If the topic goes off-topic, I'll lock it permanently.
