Gangway! is a three-column theme for WordPress that’s well-suited for group or team blogs. Developed by the Performancing team in cooperation with Forty Media, Gangway! is focused more on the content, and less on heavy visuals. Blog posts, links, archives and authors are presented in a grid-like fashion, to give that organized feel.
Update: Gangway has been updated for compatibility with WordPress 2.7 and up. Download the latest version here.
