Jamba-Warning has several options that when set will send a warning from any character (slaves and/or the master) to the master. These warnings can be displayed to the master in a variety of ways.
Warn If Hit First Time In Combat (Slave)
Tick this box to warn the master the first time the slave takes damage while in combat. This option is useful if you get an add that aggros onto one of your slaves while your master is busy tanking other mobs.
Warn If Target Not Master On Combat (Slave)
Tick this box to warn the master if the master is not the slaves target when combat starts. This option is useful if you have set up your slave's macros to use the [target=targettarget] macro option and you enter combat with your slave still targeting a dead mob (that it just looted for a collection quest 
).
Warn If I Stop Following (Slave)
Tick this box to warn the master when a slave stops following (usually the master). This warning will only be displayed if a slave stops following for an unknown reason. For instance, if the slave stops following because a movement key was pressed or another /follow was requested, this warning will not be raised.
Warn If My Health Drops Below
Tick this box to warn the master when a slave's health drops below a certains percentage (which is entered in the box below).
Warn If My Mana Drops Below
Tick this box to warn the master when a slave's mana drops below a certains percentage (which is entered in the box below).
Show Warnings In Default Chat (Master)
Tick this box to write the warnings to the master in the default chat window on the master character's user interface.
Show Warnings In Raid Warning (Master)
Tick this box to show the warnings to the master in a raid warning style. This style invloves the message being displayed in large orange letters accross the middle of the screen with a warning sound. It is very good at getting your attention.
