PhpBB

PhpBB is a bulletin board system that was popular in the early 2000's. It was the Nanowrimo website used for its forum system from its start in 2002 until 2003.

Since it is only a forum system, it does not feature any content management or any methods for load balancing or managing database queries. It also has poor defenses against spambots (an increasing problem over the internet) so it is not as popular nowadays. These options became necessary to handle Nanowrimo's increasing traffic, so it was eventually abandoned in favor of Xoops in 2004.
