Thanks 7272andy, but OpenProj has not being updated since 2008 by the user reviews here:
http://sourceforge.net/projects/openproj/and I need a modern tool that can interface with "The Brain" mind mapping software. Since I installed this I am using PCLinuxOS more than Windows

and I am better organized, unfortunately it lacks project capabilities.
Thanks nixus, I selected The Brain because it was recommended by David Allen in his website, although for me, xMind is more intuitive and easy to use. Now that I forced myself to learn The Brain I am happy with it. I am trying to implement GTD methodology, but I would like
the integration among mind mapping, Goals, Planning, Projects, tasks, GANTT, PERT, to-do, agenda, contacts, notes and journal. Might be I am asking too much for a single tool.
My other problem is selecting a GTD tool to interact with The Brain, nixus have you seen and tested some of these GTD tools? If yes, would you share your results and conclusions?
