"For years, the topic of allowing multiple accounts to manage a Google Place listing has been a hot and often requested feature.
The issue comes up often where someone claimed a listing but needs to transfer or also delegate permission for someone else to manage a business listing within Google Maps / Google Places.
Well, it might be coming soon - maybe? "
Hopefully this will be a reality soon, I think Chris would like this a lot!
