All,
The first release of the Bower E-mail Sorter has been posted on our Sourceforge account. Built as part of an undergraduate project at the Australian National University, Bower has implemented three e-mail sorting algorithms; a simple sorter, a clustering algorithm and a Bayesian-based tournament algorithm.
An XPI package is available for public installation and review. Beware that this project is still in beta and may contain bugs.
Sorting is still slow, due to use of Javascript, but provision is made for further implementation in C or C++.
Enjoy!
