When I tried to use neil@xxxxxxxxxxx, I got no mail but the modem suddenly dialled out! -- Neil Williams #-#-#-#-#-#-#-#-# linux@xxxxxxxxxxxxxx neil@xxxxxxxxxxxxxx neil@xxxxxxxxxxxx www.codehelp.co.uk -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
