This is a very simple addon, but it really rocks for less skilled players like me.

Since it's so hard to keep track of my followers health in instances (And tank, hold aggro, dps etc...), I wrote an addon to alert me when my alts are taking damage. Not only does it alert me, but it also displays what key I need to press to heal that alt.

So instead of having to:
Watch my alts health bars
See they're taking damage
Figure out what toon it is
Figure out what key is mapped to heal that toon
Press that key

I can just:
Read the alert
Press the key that the alert tells me to press

It's pretty simple:
When anyone, besides the tank, is below 75% health it displays a warning message in YELLOW to press the exact macro that will heal that toon (G1, G2, G3, G4). It also plays an audio alert.
When someone is below 25% it'll display the warning message in RED. It also plays an audio alert.

What you need to do to make the addon work for you
This is the important part. The addon will work out of the box, but you'll need to edit the following file: Lowhealthalert.lua
Change these lines so they correlate to your team members:
Code:
--- change these values for your team
local p1 = "1-1-1 Sweetcups";
local p2 = "2-2-2 Sweetum";
local p3 = "3-3-3 Sweetpee";
local p4 = "4-4-4 Sweete";
So I'd simply change
local p1 = "1-1-1 Sweetcups";
to
local p1 = "G1 Dkkiller";

If the person in the party1 position was DKkiller on my team, and if G1 was the key I needed to press to heal Dkkiller.

Here's a link to version .1 of the addon . I plan to write a interface so you don't have to edit the LUA file!
