The company I work for has some project management issues. It's not that it doesn't work but that I get the impression it could work much better.
I'm looking for a good, web-based, project management tool.
I've been playing with dotproject which I believe is excellent but I'd like to hear some other approaches (if any). I'm specially interested in opinions of people who can tell me why their choice is better than dotproject as that's the project I'm familiar with.
I'm well aware of this other question in stackoverflow) but, any recommendations for free pm software?
Edit: I'm interested in real life experience. I've had a look over all the free pms on Wikipedia and I really like dotproject but I'm about to show it to my boss so I don't want it to blow up in my face later on.
Edit: Sorry about spelling, I'm not a native English speaker and I don't see anything wrong with the text so if there's something wrong you can point it out or edit if you have edit permissions.
Edit: Ok, here's the thing, this is like a personal project of mine. I'm trying to improve project management in my company so I decided to look up different project management tools, input all the data for the project and then show it to my boss. That's why I need it to be free, because if I tell him "it's great but it's gonna cost you XXX$ he will just ignore it (every company is like Dilber's ...) so I need to tell him "You're gonna get it for free"
Edit: Sorry, I'm editing a lot but, we're more or less 150 people working on developing the project (there're more people from marketing, comercial, etc)
