On the website, there are discussion messages and the user is made aware of new messages through a 'New Discussion' icon next to the link to the Discussion webpage. The user clicks on the icon and proceeds to the discussion webpage which lists all the messages by subject name. The user views the new message by clicking on the message subjects where it then showed in a pop-up window. When the user is finished reading the message, he clicks closes the pop-up window.
Back on the main discussion page, the user still sees the 'New Discussion' icon next to the link to the Discussion webpage. Even when he refreshes the page, he still sees the icon. Even when he navigates to another page in the website, he still sees the icon.
