Many groups do not need hierarchy.
A circle of friends, a hobby group, a volunteer team, a neighbourhood community, or an informal association may work best when members participate as peers.
In Clozeu, this is represented by a Standard Group.
A Standard Group is non-hierarchical. It need not revolve around one permanent controller. Members participate as equals, while responsibility can be shared according to the group's governance.
This reflects how many real groups already work. People join because they are part of something together, rather than simply being users under one administrator.
The structure can also support continuity. If one member becomes less active or leaves, the identity of the group does not have to depend entirely on that person.
A Standard Group works well when the group is fundamentally a community of peers.
For groups built around participation, shared history, and mutual involvement, this can be more natural than structuring the group around a permanent hierarchy.
