I can as well. In my view of the issue I believe that allowing everyone on listB to submit is the better option as I can easily make a list composed of those allowed to send unmoderated to listB, call it listB2 and add listB2 to listB then use listB2 as the list allowed to send to listA (all of this assuming recursion is implemented).

But that would be confusing to the members of listB. They would have to realize that they are not really a member of listB, but that they are actually a member of listB2.

So, if you are going to do that, and perhaps for any inclusion that is transparent on message delivery, an attempt to change delivery preferences on listA should take the user to the listB2 preferences.

However, if the delivery of listA is done by publishing a copy of the message on listB, then, for the purpose of preferences, the listB user should not be considered a member of listA.
