It's okay, we have more than enough people to watch the activity board for further vandalism strikes, but you're more than welcome to be on the lookout on any signs of vandalism on the activity until the vandal watch expires on August 16 in 8 AM in Eastern Standard Time or when a vandal attack occurs after the expiry on the vandal watch notice.

(Oh, and mind that one language there, just to remind you!)

In short, it's optional to moderate the Wiki activity board, but like I said, you're more than welcome to do so. Thanks for the question!
