37 Signals BaseCamp is an obvious choice, but it is costly for a start up. I also was interested in project management software and wanted to find something comparable to base camp that was free. I ended up finding one, it's called http://www.teamlab.com/ http://www.teamlab.com/. They seem to have everything base camp does at the same quality level, except it is free. I'm going to be using it for my projects. Has anyone else used this?
