What you actually wish to achieve is not entirely clear. You may get more useful responses if you elaborate on the problem you are experiencing. For example, are messages that SHOULD have been sent to the "command interface" (such as subscribe or signoff) being distributed to the list population? Or do you wish to block the processing of such commands? >>> [log in to unmask] 3/15/2007 1:10:28 PM >>> Hello, Is there a way I can prevent subscribers from issuing commands to the list altogether? I simply want subscribers to be able to post messages and nothing else. Is that possible? Thanks, -Mike
