Social groups
The social groups are the primary areas (circles) where social interactions occur.
- Social groups have resemblance to Facebook groups. 
- Unlike FB groups, social posts are always grouped. There is no personal space, unless a personal group is defined. 
Important attributes:
- Code - this is the unique code of the group. It is also used as a slug which forms part of the URL for the group, posts, etc. 
- Name - the universal name of the group.
