Creating a private online space for your friends, donors, collaborators and partners to get together can have all sorts of useful consequences - apart from not needing to buy a ticket or drive to get there, they may also be more likely to post ideas, more willing to share information, or feel a stronger sense of belonging because of what they get access to in the private space. A members-only area on a website can be anything from a modest filing cabinet of privileged-access docs to a discussion space for conference agenda planning, an address book of members' contact details, or a collective calendar.
