PunBB is a fast and lightweight discussion board. Its primary goal is to be a faster, smaller, and less graphic alternative to otherwise excellent discussion boards like phpBB, Invision Power Board, and vBulletin. It has fewer features than many other discussion boards, but is generally faster and outputs smaller pages.
UseBB is a PHP/MySQL forum package. Unlike other popular forum systems, it does not strive to have as many features as possible, but to be one of the easiest and most usable forum packages, limiting the basic feature set to only the essential. It is an ideal solution for small to medium-sized Web sites which require an easy to use forum package without the bloat, that produces standards compliant output, and is secure and easily configurable.

Changes can be made on a preview site and published at a later time on the live site. Fully flexible URLs allow the replacement of existing static Web sites.
CGIForum is a highly configurable template-based discussion board. It supports expandable/collapsible threads of unlimited depth, name registration with password encryption, multiple sections from within a single script, previewing, searching, and marking of new entries.
