Heh, /this/ thread. =:^) I obviously lost track of the thread I was replying to. Which in a way makes the reply even more forceful, as it's obviously generically targeted, not just at this thread. Even if I were so devious as to arrange that deliberately (I'm not and I didn't, FWIW, but of course if you suspect that than this assurance won't mean much either). -- Duncan - List replies preferred.
