Well I'm glad Brendy didn't run into the elk family. When I'm in a temper it screws up my driving.But I can't see why it matters whose address book you are in if you can click the Block Sender option and the missives won't get through anyway.
But then I don't understand this stuff. I've never got round to using the "send mail to group" thing myself anyway. I prefer the one to one approach. Though you sometimes get some good jokes from group mailings.
