For the first question, I don't know if someone can alter other users' subscription options "accidentally." But if one sends out a forged e-mail message to the LISTSERV, it is possible. On my list, to prevent such unpleasant incidents, I have the following line in the list header: * Validate= All,Confirm This way, each command which may change a subscription flag has to be confirmed by the e-mail account owner (a one-way forged message wouldn't complete the change). For the second question, I don't know the answer, but I'd like to know it too. Kind regards, Jim, CHPOEM-L list owner -- Go isn't everything. Go is the only thing. -- zhuge
