Create a Discussion Board with SharePoint 2010
A SharePoint 2010 team site is created with a Team Discussion list. You can use this one, delete it and create a new one, or create multiple new discussion boards for your team to contain the discussions to more defined areas.
If you prefer a more specific name for the predefined discussion board, you can rename it, or delete the predefined list and create a new one. The advantage to creating a new one is that the URL matches the list name.
To create a new discussion board, follow these steps:
Choose Site Actions→More Create Options, or click the All Site Content link on the Quick Actions menu and then click the Create button.
In either case, the Create page appears.
Click the Discussion Board link under List and then enter a name for your discussion board in the Name field.
Click the More Options button to add a description in the Description field.
Select the Yes or No radio button to determine whether you want to show the discussion board on the Quick Launch menu.
Click the Create button.
You see the list page of your discussion board. Note: In the Current View section, discussion boards are arranged by subject.
