I was wondering if there were any free tools for producers to keep track of the team, development being made, work left to do, etc etc.

Thanks!

Continuous deployment of build and a notepad/pen combo?

Negatif.

That wont help me keeping my team updated with everything.

Check out Mantis and Tortoise SVN.

And Google Docs, Google Spreadsheets, Google Calendar...

Oh, and Dropbox.

Moving to Business.

I have been searching for a long time now and i was wondering if there were any free software like Planning Force that i would be able to use on my server and have my whole team use it?

Thanks
