A/I PSI Jabber Client Configuration Howto
Install psi and launch it: it will prompt you with the "Add Account" panel.
In the "Jabber ID" field fill in your e-mail address and click on the
"Connection" tab.
It would be better not to
fill in your password at this stage (because it would be saved in your
Preferences and thus in your filesystem): you can always type it every time you
launch Psi.
Mark the checkbox "Use SSL encryption" and in the "Host" field fill in
"jabber.autistici.org".
Check that the connection port is "5223" and move on to the "Preferences" tab.
Mark the "Ignore SSL warnings", and save your configuration. Now you can launch Psi, type your password and chat using jabber via Psi client. :)
