Just a quick follow-up: The missing email to fom was sent in reply to Arnon Avron's http://www.cs.nyu.edu/pipermail/fom/2006-March/010129.html ARNON: Did you by any chance receive that reply from me, directly? If so, please could you send it back to me, so that I can send it to fom? (I didn't keep a copy of it.) Thanks-- Neil
