automatic notification
In order to be automatically notified about new messages, it is necessary to activate the subscription in a topic or in a sub forum. In a forum area you can find the setting in the title box on the right (under the button "New topic"). Within a topic you can also see the option "Subscribe to this topic" under the box "Related topics" at the bottom left. If you have subscribed to a topic or forum, you will automatically receive a mail when a new message is sent. After that no further messages will be sent until you have visited the forum.
