(First Things First)
So far none of the free project planners do time accounting very well. Well, neither does ftf but it DOES let you do clumsy but functional time accounting. What do I mean by time accounting? You can tell ftf how many hours a week you have for a class of projects (example: work and home) and then when you input a time required for a project and what bucket to take that time from then ftf will estimate when you will be done with the project. If you will be late then ftf blocks that out in red.
Note that you should download and install STk from kaolin.unice.fr and ensure it works before attempting to get ftf working. ftf should work on most Unix like oses and on windows (untested).
There isn't any! See the file COPYING for details. Generally I do like to hear from folks trying out ftf and I do intend to continue improving it.
