I am a big fan of Microsoft Project: I think it is fantastic not just for work, but for home. If for some reason you can’t get a copy of that software, I highly recommend that you consider this software: OpenProj – Project Management | Free Business & Enterprise software downloads at SourceForge.net. It’s free, and it looks very similar to the software from Microsoft. It will even open and work with files that come from Microsoft Project.
I highly recommend both tools.
