XEP-0107: User Mood
A user MAY provide a mood extension in a specific message in order to lend a defined emotional tone to the text.
Example 5. User Provides Mood in Message \<message email@example.com/pda' firstname.lastname@example.org' type='chat'> \<body>A thousand times good night!\</body> \<mood xmlns='http://jabber.org/protocol/mood'> \<sad/> \<text>curse my nurse!\</text> \</mood> \</message>
This stanza works if the server doesn't support PEP and send my mood in message.It would be nice to have this option in gajim!
