One thing I do notice is that the administrator and moderator addresses
listed in the GENERAL OPTIONS web admin page of each list is the same
address (newsletter at knifecenter.com).
Further below, on that same page, there is an option that says, "Should the
administrator get notices of subscribes and unsubscribes?" I have that
checked to YES.

Could it be that because the administrator and moderator addresses are the
same (newsletter at knifecenter.com) and because the administrator is getting
notices of subscribes and unsubscribes, that the message is being sent
twice? I'm assuming the moderator gets notices of subscribes/unsubscribes
automatically.

Let me check. (It may take a while ... because there are a couple
hundred/thousand subscribe/unsubscribe messages in queue.
