Hello folks: With Listserv 1.8c on an IBM VM/CMS system, how can subscribers to a list be prevented from ever selecting the CONCEALED subscrpition option? On one particular list, the owner (not me) does not want anyone to have a concealed subscription entry. The documentation does not shed any list on this. Any info will be appreciated.
