  As a teacher
  I want to set up a forum that allows each person to post one discussion topic

  Background:
    Given the following "users" exist:
      | username | firstname | lastname | email                |
      | student1 | Student   | 1        | student1@example.com |
      | student2 | Student   | 2        | student2@example.com |
      | student3 | Student   | 3        | student3@example.com |
    And the following "courses" exist:
      | fullname | shortname | category |
      | Course 1 | C1        | 0        |
    And the following "course enrolments" exist:
      | user     | course | role    |
      | student1 | C1     | student |
      | student2 | C1     | student |
