What I have never understood is why people join a particular group (Which obviously talks about something of interest to them), and do not want to keep up with what the group is talking about. Special Notices are almost like No Email as they are hardly ever sent out, so that setting should be adequate to any lurking member. There are times when moderators need to communicate something important to the group, so allowing a member to select the No Email option is a nonstarter to me.
