Wonder Wall moderators (teachers, scientists, and curators) and members (students or club members) log in to that address.
Wonder Walls, moderators, and members are organized into groups, which are organized into programs. Here is an example structure of the Wonder Wall account for the Michigan 4H Children's Garden.

Organizations who have purchased a license can create as many programs and groups as they wish, but they cannot exceed the limit of how many members and moderators can be logged in at the same time.
Creation and management of programs, groups, wonder walls, members, and moderators is supported by the Wonder Wall Manager system. A licensed organization has their own manager account.
