To Tony Williams and other members of the group-- I was afraid my comment on the conversational tone change of our group would be perceived as some sort of slight towards our esteemed on-line editor. As I said previously, I don't envy him the job that he does, and feel he is needed. I simply wondered aloud how we could keep this group from being a research service for undergrads (and some grads) who sign on to get a couple of facts and then unsubscribe when their term paper is done. ---- To signoff SCREEN-L, e-mail [log in to unmask] and put SIGNOFF SCREEN-L in the message.
