I am a co-owner of CIUW-L@PLEARN (SUBSCRIPTION=OPEN) and I am intrigued by the following phenomenon: sometimes the owners receive just notification about new subscriptions, signing off etc., and sometimes they receive REQUEST for subscription, removal, change of an option etc. My first guess was that this fact can be related to the rather unusual setting CONFIDENTIAL=SERVICE. I have changed it to CONFIDENTIAL=NO but it did not helped. I will appreciate your suggestions. JSB Institute of Informatics, Warsaw University
