The 'Open Directory Project' DMOZ.org, one of the most important manually edited directories on the web has opened it's doors for business again and is accepting Site Suggestions, the service had been experiencing problems since October.

UPDATE: January 13, 2007-- The Site Suggestion, Update Listing, Editor Reinstatement, and Forgotten Password forms are available again. New editor applications are still disabled and we are still not able to check on the statuses of previous applications. As well, the public abuse reporting system, editor feedback, and any other feature for which the "Service Temporarily Unavailable" message is still appearing are still not available. We have no ETA for the return of the features which are still down. Please be patient and, again, we ask that you not start threads asking when those forms will be available again--we will update this announcement when we have further information.
