Am I correct in believing that if TOPICS is to be enabled for a list already in existence, the default for all the current subscribers will automatically, without further configuration of the list header, be ALL? That is, current subscribers will continue to receive all messages posted to our (moderated) list until they change individually their own configuration using the SET TOPICS command. Put another way, if the listowner wants ALL to be the default value, a DEFAULT-TOPICS line is not necessary in the header. Thanks, in advance. Ken Harris Slippery Rock, PA
