Microsoft Office Groove 2007

From Microsoft:

Office Groove 2007 is collaboration software that helps teams work together dynamically and effectively, even if team members work for different organizations, work remotely, or work offline. Working in Groove workspaces saves time, increases productivity, and strengthens the quality of team deliverables.

Work together dynamically. Keep your team, tools, files, and information in one place. Create a Groove workspace right on your computer with two clicks. Invite your colleagues, partners, and customers without worrying about networks or servers. Add tools to support your team's evolving needs: file-sharing, discussions, meetings, and business forms.
