There are three possible acts in a VVV Library:

• every one can propose texts' elements,
• each one can choose among those elements,
• any one can delegate his choices.

The choices for one element are assembled into an acceptation level. It is a number calcultated using the number of votes agreeing minus those disagreeing, divided by the number of active persons (a person is active if she has at least one active act in the library).

The two acts "to propose" and "to choose" correspond to the foundations of participative democracy. The third act, "to delegate", is the foundation of representative democracy. It allows every person to delegate her choices to others and to represent others' choices. A delegation can be overriden with sub-delegations and choices.

Acts can be modified at any time, except for what has been proposed publicly, and be rendered inactives after a community chosen period.
