I, too, am with the view that the 'yart' card is rude. We are all such writers here that we could at last summarize points of view that we remembered from a previous discussion or just mention that the topic had been covered a while back and then recall an interesting fact or two frm that discussion. But to stop discussion altogether, especially if the topic hasn't been discussed in a while? Balderdash!

Now if the topic has been covered, say, last week, or is currently being discussed? Well, sure. Send the poster on to the active thread--or recently deceased dead thread.
