Sorry. I mistyped. What I meant to say was I was getting them in viewer, not email.
A fuller recap of the situation:
I currently have a single avi. All other accounts I've had in the past are long (as in years) gone. I connect using Firestorm Viewer. I have been a member of a number of groups and left those groups. I have, on occasion, still received Group IM sessions from those groups while logged into the viewer. This is not a matter of email notification, which are turned off except for L$ purchases. I'm curious if anyone else has run into this, and, if so, how to stop it
