The output is absolutely correct. Note that in your case .bb (&x ^= POSTMASTER) and (&x ^= OWNER) evaluates to TRUE, so the conditional block is executed. You didn't say which block was executed after that but I'm assuming it's the "other people" block. And that's correct--it <is> possible for "other people" (in this case only the list owner(s) and postmaster(s)) to see that someone is subscribed to the list. Naturally you can feel free to discard this block and hard-code the message if you want. Note that you left out the closing .eb that should follow the line just issue a "SET &LISTNAME CONCEAL" command. however. Nathan
