Although you can practice project management on your own, you'll learn faster if you collect a team, and take turns being the project manager.
Even if everyone is in the same room, it helps if everyone can edit a document at the same time. You can place all PM documents in one etherpad at
etherpad.mozilla.org (simply click on "Create a new public pad" and send the URL to your teammates). You can also use collaborative tools for
drawing or
mindmaps.
Here is a
blank template, including the charter, plan, progress report, and evaluation on one etherpad.
Before your first exercise, at least one person in the team should visit the
Ludopolis website so they can act as a consultant for the other team members. They should have some idea about: action points, players vs. citizens vs. traders, goods, and terrains.
Don't make it too easy for yourselves, and have fun!
