Digsby Portable

Instant messaging client Digsby, winner of the Best System Tray Applications Hive Five and all-around Lifehacker reader favorite, is now available as a convenient portable application.
The initial release of a portable version of Digsby couldn't handle updates without breaking. Those bugs have been ironed out, though, and now the portable version updates right alongside the desktop version without a hitch. The author's site is in German, and for some reason switching over to the English translation makes the download link vanish. The link below is a direct link to the download to save you the hassle of navigating the site; if you want to visit site before downloading the file, follow this link. Digsby Portable is freeware, Windows only.
