I was hoping experienced monks, like you, would help me more clearly define these actions. I had no idea about the private message capability.
Regarding searching for old nodes, what you said is what I meant to say. If I don't login and then post something, and you don't login and then post something, there is no way to distiguish the author of your post from the author of my post. Both posts are from the same author, namely Anonymous Monk.
I will update the OP (somehow) using the information you provided.
