         CREATE DATABASE message_board;

    CREATE TABLE message(
      id INT PRIMARY KEY AUTO_INCREMENT,
      author VARCHAR(50) NOT NULL,
      due DATETIME NOT NULL,
      posted DATETIME NOT NULL,
      msg TEXT NOT NULL,
      dropped ENUM( 'Y', 'N' ) NOT NULL DEFAULT 'N'

• Create a new user and give it appropriated permissions:

      GRANT SELECT, INSERT, UPDATE, DELETE
        ON messsage_board.message
        TO board IDENTIFIED BY 'b0aRd'

• Test if the plugin is correctly installed:
  • Open a MessageBoardTestArea^? and insert %MESSAGE_BOARD{ messageOrder="DESC" }% into the topic. Preview, save and try to post a message.
