I've had my board closed for a couple of weeks--long enough to allow members to retrieve any original work they wish to keep before I shut the site down permanently. In recent days, the moderation queue of this closed board has ballooned, for some reason, to hold almost 2,000 items. I have no idea of why this is happening. But before I take the board offline, I want to delete all of the moderation queue items in case I restore the forum at some point. How can I do this?
