Introduction
| Presence |
|---|
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.
