Feature: Newsletter notifications for users
  As a Peer
  I want to receive notifications in my email box
  So that I am aware of the summary of upcoming proposals for next assembly

Scenario: Newsletter every week-cycle for valid users
   Given I am an peer and have a validated user
   When a week-cycle occurs
   Then I receive a newsletter with a summary of the existing proposals for next assembly meeting
