Yes - though my reading of Popper is that he's very emotional - and has at times contributed well to discussions and at other times was really grumpy - and there were times he and I got along (not often). It seems genuine of him to want to delete his comments and return as another user. Most of us have no reason to return to our earlier comments. Name recognition (and social memory) night be gone, however, unless he says he's the previous Popper. I think we'll see him again.
