Managing a social network comprises creating a unique first group code, creating a first personal wall including a link to the first group code, and creating a first group wall for the first group code. The first user receives an inquiry to join the first group code from a second user. The first group code is exchanged between the first user and the second user. The first group wall is converted from a locked to an unlocked state with respect to the second user. A second personal wall is created for the second user, the second personal wall including a link to the first group code. The first user is restricted from viewing the second personal wall, and vice versa. The first user can share, and the second user can see, a subset of data from the first personal wall with the first group wall, and vice versa.
