We had looked high and low in the project management software market or something that would fit our needs.   What originally attracted us to Ubuntu Project Management Software was that it was collaborative project management software.  We could work with them to insure that our own project management tasks were identified and included in the program for our use.  This seemed to be so much better than some of the off the shelf models that were generically designed to be a one size fits none model.    It has provided us with our needed project management solutions and made us feel part of the Ubuntu community at the same time.
