How to connect Sugar to a Jabber network
Due to scalability issues, jabber servers can currently only handle up to about 150 users at a time. It is best if specific communities run their own servers - by geographic region, by special interest, whether for kids/parents only or adult users...
To set up your own server, see instructions at Run your own jabber server.
Connecting to a community jabber server
If you want to connect quickly, simply open terminal. Then type the following commands :
sugar-control-panel -s jabber jabber.server.url
replace jabber.server.url with the jabber server you with to use
then restart Sugar (warning: close activities first to save) by pressing ctrl+alt+erase, then go to the neighborhood view and have fun!
