However, I don't think Brad O. is an administrator - so my reasoning may not be valid. I will check the message headers to see what the route my notifications are taking.
Yeah, I'm not an administrator. I noticed that the duplicate Emails (at least in one case) are 5 minutes apart from one another. Maybe it is something our administrator is doing?
I'm thinking that this isssue could be a result of something as simple as clicking a "SEND" button multiple times. I should probably ask other members of our ward if they also get the duplicates. Since I do not have admin access, I cannot do any testing on my own.
