On this tab, you can see a list of all message boards on the current site. Using the Board name field above the list, you can filter the displayed message boards. You don't need to enter the exact name, you can enter only a part of it and the list will display all message boards with name containing the entered expression. It is a good idea to give your message boards well-descriptive names so that you can tell one from another and search efficiently.
Message boards can be Edited () and Deleted () on this tab.
Editing message board properties
Remember that once the message board is created (after first message or subscription), you cannot make changes to these settings in the web part's properties. You can only modify values in this section of the administration interface.
Detailed information about the Message boards module can be found in Developer's Guide -> Modules -> Message boards.
