Mimi,
>>> For our group, it would be better if the Owner actually was a different level. As the owner, I do not want the moderators/administrators to have to deal with a bunch of emails that are technical,
No need for a different level for what you want to do, ?and ...
>>>?If I go on vacation, I would like to be able to flip a switch and have the moderators get those emails in my absence. But that is not possible
the functionality you are looking for is already there; just like you can set your own notification preferences, so you can of the mods:
Logged-in as the group owner, go to Admin -> Members, and select Mods from the blue button. ?Then click on the mod you want to modify, go to their Moderator Notifications area and disable the ones you don't want that particular mod to get. ?This will stop them from getting those emails.
Cheers,
Christos
