I do appreciate the quick replies to my 'concerns'. Okay, so your MOD uses this field, as well as vBulletin itself. That explains why I'm getting what I'm getting.
It doesn't really make sense to have vBulletin send Administrators emails about "Users Awaiting Email Confirmation", unless perhaps, it's so we could opt to activate the user directly -- if we were to choose to do so. But that isn't optimal, IMO.
If your MOD were to add it's own email field, and use it exclusively when the registration email was acknowledged, then as Administrators, we would have a choice of receiving one or the other, both, or neither, which I would find most desirable.
Again, thank you for your good work, and for entertaining my observations and at times, confusion.
