So funny story... the quote emails aren't a default feature, they are part of the add-on we installed to give us @ user tagging support.
As far as I can see there is no interface for admins to adjust user preferences for this plugin, so without messing with the database (which I'm not going to do) I can't stop quote e-mails on a per-user basis.
I've manually promoted your account. You should be able to access settings now.
