I got that listserve address wrong. The "subscribe" message should go to: [log in to unmask] The mailing list itself is [log in to unmask] Sending the "subscribe" message to cns-tesla instead of to listserve will only send your message to the list recipients, and won't subscribe you to the list. There is also supposed to be a cns.tesla newsgroup, if your internet service gets new groups. .....................uuuu / oo \ uuuu........,.............................
