Thanks for all the clarifications... I now need to add 100 association members to my list. Some of them are currently FULL list members ( I don't know which) the rest are ONLY interested in this one NEW Topic. I have set my topic-default= -newtopic I plan on doing a quiet add for all 100 members. Some will already have been subscribers... I guess I will need to then look at the report and isolate those who have been "already subscribed" Those who are not "already subscribed" will then be put through a batch quiet set oandp-l topics: -all,+newtopic for newuser*@domain It sounds a bit cumbersome, but it looks like it will work. Does anyone have a better idea? Thanks. Paul P.
