We need a way to give a link to an “unsubscribe” option when we send out mass mails. We could embed a special link into each message with a token for the user or the email address. That way, the person just goes to the web site, sees their email address, and clicks “Unsubscribe.” Or, we could prompt people to log in, but that might seem fishy. Need to define how this should work and add it to the members component and the messaging part.
