Skype for Mac OS X
Mood messages
Mood messages are simple little messages that you can type telling your friends the mood you are in, a witty comment, quote or any random piece of information you'd like everyone to see. Your mood message will be displayed next to your name in your friends Skype Contact List.
To set your mood message click on your profile name on the top of the Skype window to drop down the mood view or go to “Account” > “Edit My Profile” to add a mood message.
