Introduction

Presence
Mesh View

One of OLPC's core principles is Connection:

"The children in the neighborhood are thus permanently connected to chat, share information on the web, gather by videoconference, make music together, edit texts, read e-books and enjoy the use of collaborative games on line."

Sugar provides a collaboration framework for activities, which provides presence and data sharing.

This page is your guide to the state of Collaborative Activities on Sugar: developing them, using APIs and techniques, and assisting others in the development community.
