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"?
