Create A Forum - Support Forums

Just wondering is there a way to totally clean up sections like delete all posts at one time instead of having to delete the posts individually?In this case i'm talking about mod forums and the delete Bin........

Maintenance > Forum Maintenance > Topics
Set the number to "0"
Choose the Boards you want the topics removed from.
 
Its that or you can go to the Board that contains the topics you want to remove.
Put a check in the box in the header at the far right.
Go to the bottom and use the dropdown box and choose "remove selected"
(You need "checkboxes" set for quick moderation in your Profile > Look and Layout -  last setting at the bottom of the page)
