punBB

PunBB is a fast and lightweight PHP powered discussion board. According to the developers, the primary goal of punBB is to be "a faster, smaller and less graphic alternative to otherwise excellent discussion boards such as phpBB, IPB, and vBulletin." PunBB has fewer features than many other discussion boards, but is generally thought to be faster and outputs smaller pages.
