YaBB is one of the first free, open-source bulletin / message board systems in existence, having been around since 2000. Many of the other systems started from YaBB or were based on it. YaBB is proud to be one of the most secure bulletin boards in existence with many security, spam-fighting, and flooding-blocking tools available, including the unique "the Guardian" system. Some of the many features include RSS feeds, full administration and settings, integrated help, UBBC code, news, private messaging, buddy lists, advanced post editor, private boards, statistics, favorites, notifications, email system, advanced but easy templating, and much more.
