What free project planning tools like Microsoft Project are you using?

Question

I would like to learn what tools there are and whether you have positive or negative experiences with them.

For me important features are

1. Nesting of tasks within tasks
2. calculation of effort summaries across task hierarchies
3. dependencies between tasks
4. resource allocation
5. Gantt or other timeline view

I stumbled across OpenPROJ and it sounds promising. Any experiences?

Thank you!

Answer 2

I have used a bit OpenPROJ and it does what its needs to do and resembles very much to Microsoft Project. So much that it quickly gets very complex to maintain project data (like it is the case with Microsoft Project). I have to say that the last version of Microsoft Project I have used is 2000, so I'm not comparing with the latest version.
