We wish to create some sublists with the restriction that you must already be subscribed to a "main" list in order to be allowed to subscribe to the sublist. In other words, you can subscribe to list B only if you are already subscribed to list A. I tried Subscription= (listname) but this was not recognized so it defaulted to Subscription= By_owner. Anyone have any ideas about this? Perhaps Service= (listname)?... not sure that is looking for an access-level either. Oh well... thanks for any suggestions.
