Have a general owner of some contacts that all agents can access eg [office contacts]
This way we wouldn't have to add each and every person in the office to the contact so they can access it. (time consuming).
This would make lawyers etc available and not clogging up an admins contacts list.
Also this would be useful when an agent has a contact on a listing we could add [Office Contact] to the permissions temporarily while listing is live - as at the moment we have to add all the agents one by one to the permissions, and then remember to remove them when it is withdrawn or sold etc.
