1. Works with desktop Google Talk client, not iGoogle yet 
1. This may change once parts of Gabble's Jingle code have been migrated to Wocky, and Salut ported to Wocky. 
1. Audio/Video chat no longer works in MSN due to Microsoft removing the necessary servers.

## Methods of being invisible on Jabber

Gabble supports: 

* Google Talk's [[shared status extension|http://code.google.com/apis/talk/jep_extensions/shared_status.html]]; 
* [[XEP-0186: Invisible Command|http://xmpp.org/extensions/xep-0186.html]]; 
* [[becoming invisible using privacy lists|http://xmpp.org/extensions/xep-0126.html]]; 
* the pre-XMPP [[<presence type='invisible'/> extension|http://xmpp.org/extensions/xep-0018.html]]. 
This should mean, in practice, that Gabble supports being invisible on any Jabber server where it's possible to be invisible. (This, notably, does not include Facebook.)
