I kindly disagree. I think what we pick up is our responsibility. It's one of the reasons I have that rule on my own games, "If you don't have it written down, you don't have it." Writing notes is beneficial in many ways not just for remembering loot.Sherwood, you are sneaky. I had forgotten about those credits too.
Besides, anyone running a game has enough to do. As a Player, I feel I can do my part to contribute (like mentioning these credits and items). =)
