So, take a stroll down memory lane to remember all of our past Word of the Year selections.
To lock and unlock Tell Me When, type "/tmw" or "/tellmewhen".
Note that Tell Me When also has two custom Unit IDs, "maintank" and "mainassist", used to track raid maintanks and mainassists.
At the bottom of the icon editor, there is a dropdown menu that can be used to copy icon from other icons, or to import icons that other Tell Me When users have sent you.
The meta icon is a unique icon type in that it is not configured like any of the other icon types.
Instead, the meta icon is simply a list of other icons to check and display.
Remember that buffs and debuffs sometimes have different names than the items, abilities, and talents that provide them.
For example, the Death Knight ability Icy Touch applies a Do T called Frost Fever.
This allows you to combine many different icon into one, central spot instead of many different places.
If you selected a buff/debuff icon, you will also need to enter the unit(s) that you wish to check for the buff/debuff.
Multiple units can be separated with semicolons, and more information about units can be found here and here.
If this setting is enabled, once the meta icon displays an icon, that icon will not be displayed by any other meta icons on your screen.
What this setting allows you to do is to create 'chains' of icons by setting up series of meta icons, each one checking the next, with the first meta icon checking all of the icons that the chain should display.
Like icon shown conditions, meta icons will not check icons that are disabled.
