I just wanted to chime in here to say that, at least in a vacuum, I found Rupert's e-mail to be highly inappropriate and I found Nathan's response to it to be wholly appropriate.
Rupert, I hope to never see a repeat of this incident, in which you attempt to badger a list participant and Wikimedia volunteer off-list with uninformed and irrelevant questions under the guise of "saving bandwidth" and faux concern. Cut it out.
