There is some key information that needs to be passed to team members who want to start using a team project.  Namely the TFS server machine name and also the team project name.  You can get all of this information and more in the text field summary pane that is displayed at the conclusion of the team project creation wizard.  So one trick for getting all this vital information to your team members would be to to cut-and-paste the information from the summary field of the wizard into something you can post somewhere or email to the team.
