Who CAN it be?

I always thought my "nodnurg" address was bad enough. It dates back to the time when it was thought best not to use one's own name in your e-mail address

However, we now have one of our most respected members lurking behind the nom de plume of jmcbloggins. I am not going to tell you who he is. He can do that himself if he decides to break cover. (Perhaps I should have said he or she!)
