This addon was developed and created by Healingdoom of Nazgrel.

DESCRIPTION,
The purpose of this addon is to simplify marking in heroics or raids.  It will automatically mark your target after a set amount of seconds, allowing you to focus on more important stuff than a key binding.  It can be used by a tank or a dps.  It also supports a basic kill order system, and has a option to create a Deadly Boss Mods timer to show when it will mark.

USES FOR TANKS,
In heroics it coordinates the dps
In raids as a offtank it helps for dps to see your current target due to that being the target with the most agro most likely

USES FOR DPS,
In any situation you would be the "Leader" for dps.  Whatever you target the other dps should target as well and allows you to coordinate everyone without calling targets or confusion.

If the mark moves too soon for you then open up the options menu in interface -> addons -> skull me or type /sm, and change the sensitivity higher to allow you more time.  

TIPS AND TRICKS,

You can use /sm enable and /sm disable to turn it on and off in a macro
You can use /sm time <number> in a macro to change the time allowed before it auto marks.  Uses <number> as the time.
You can use /sm mark <number> in a macro to change the mark used to auto mark.  Uses <number> to change mark.  Accepts 1-8
You can make a macro as follows....
  /target <player>
  /targetlasttarget
Where <player> is your name, to extend the time on the auto mark.  You can keybind the macro and that will reset the timer if needed.
