We've had one for 15 years now but it seems to have turned into a hindrance rather than a help. Part of a wider issue of course, but it has turned into just another inbox for me to manage with my DH having opportunity to read stuff (and not take action.)
If you have one how do you manage it, if you don't have one how do you manage admin stuff between you - just forwarding emails over?
(3 kids so lots of school stuff etc)
