There are lots of other threads still extant which are about the anonymous GUEST thing. As I've indicated, I also think the practice is irritating, discourteous and diverts attention to the person/people who go in for it, but going on about it in this thread is not a sensible thing to do.
Generally I think a bit of thread drift is fine,and I do it all the time. But I think moving off onto this issue on this thread just gets in the way of more significant discussion.
So I suggest that the place to take the complaints, or the responses to the complaints, is File anonymous guest complaints here
