Maybe this has been discussed in this group. If so, let me know and I will try and search the messages. Instead of unsubscribing from one IO group I belong to, I set my subscription to no mail. This seemed to have worked for a couple or three weeks or so, but I just got a slew of messages. I checked the subscription again and it is still set to no mail. What could have caused this? I went back in, set it to individual email, saved it, and then immediately set it to no mail. Maybe that will work for awhile.
