If your server with the forums installed resides in the United States and your content can be potenitally harmful to childern under the age of 13 (PG US Movie Rating), you must have the COPPA forum filled out and this system must be enabled and enforced.

Even if your URL has an out-of-US URL and the server resides in the US and most of your users are from out-of-US territory the system must still be enabled.
