FPF requires members to provide real names and addresses.
Since FPF's mission is to help neighbors connect and build community within the local area, all members are required to supply their actual names and full street addresses. Allowing participants to be anonymous runs counter to the mission of helping folks get to know each other. Business and nonprofit accounts also require a person's name, as well as the name of the organization.
Note that the only time your street name -- no number -- is revealed, is when you post a message.
