Are we back to the anti-Guest crap again? Kee-ryst, it's like a big turd that won't flush. There's always a great wailing and gnashing of teeth every couple of months or so.

Guests are here. Not everybody wants to join or can join; maybe they post from work and can't use cookies. Often it's an unnamed guest that provides useful information--information we might not have gotten if they were forced to register their name first or provide some other qualifier to identify themselves. The bulk of guests contribute constructively. The few that troll and flame incessantly are easily ignored. We all forget to do that sometimes, often by choice.
