Very useful project!
Has moved on from Sourceforge, last release Sept 2013, latest release on phreebooks.com is Nov 2014. Development seems to have slowed in favour of re-written Bizuno, a commercial open source package derived from Phreebooks and the owners of Phreedom. Rudimentary interface, functional but not efficient or elegant. Mouse drive, no apparent keyboard shortcuts. Covers a wide range of functionality to a small business level. Requires a reasonable knowledge of accounting, not particularly intuitive. Has a made in 2007 feel, style not particularly updated since then. Support is by searching forum, there is no wiki. A good effort by Dave & Alvin.
