After you open a topic, the time counter is enabled. After the corresponding time expires, the topic is automatically marked as read. You can change the time interval after which Web Forum Reader marks topics as read in the settings area.

Read topics are displayed and highlighted in the list so that you can easily distinguish them from active (new and changed) topics. This allows you to easily find the information you need and save time by avoiding reading the topics you have already read.

You can also force Web Forum Reader to mark all topics as read.
