   Thanks for the clarification, Eric.
 
   I take this to mean that adding topics in the future will cause
   (perhaps unexpected) filtering for subscribers that have set topics
   including OTHER.
 
   Let's say a list of interest has topics A and B. If I set topics to
   exclude B (with "Topics=A, OTHER"), then when topic C is added to the
   list, I won't receive the topic C postings.
 
   Is there a construct anything like "Topics= not B"?
 
Just wondering,
