Roles can be created and assigned to members by the organization manager.
On Whaller, roles can be used to:
enrich members' profiles with data from the organization
visually distinguish groups of people with "badges" attached to roles, that appear on their avatars in spheres
mention a set of people with the same role in a sphere (by clicking on the "@" under the message writing field)
have people in specific roles fill in specific profile fields ("Admin > Roles & profiles" > "Personalized profile fields")
assign specific rights to a given set of people ("Admin" > "Roles & profiles" > "Roles" > "Rights linked to functions")
