You can also loop the messenger messsage (option in the Video menu).

You can turn OFF the messenger in the General Preferences "Show Messages in the Video window".

Custom Message

You can also send a customized message, either a one-shot message, or you can set up a message then send it over and over whenever you want (eg: "Tip your waitress!" or "Drink Specials for the next hour!"). To show a one-shot message, pick Video->Messenger Message, then type your message and it will immediately be shown. Alternately, you can pick "Video->Enter Custom Messenger Message" to enter a message that will be saved for later. Then, at any time you can pick "Video->Show Custom Messenger Message" to show that message.

Messenger Rotation

If you have a rotation going, it will say who is singing the next song. You can cause this to happen at any time by picking from the menu: Video->Messenger Rotation:
The default "Template" (meta tag list) for the messenger rotation is "[nick]: [name]". This means first show the "nickname" of the singer (default being the Singer Name), followed by a colon, a space, then the Song Name. You can use any song "Xattr tags" from this list.

If you want to show ONLY singer's nicknames, then you can change the pref to just be "[nick]". The "secret pref" is "Messenger Rotation Template". To set this in kJams 2: the proper python pref command is:

kjams.pref_set("Messenger Rotation Template", "[nick]");

Aside: Meta tags can only be 4 characters long. Since "[name]" is so generic, I suppose the template for "song name" should have been "[sogN]" and "Singer Name" should have been [sigN], but i can't change it now.
