This addon allows party members to assign raid target icons to mobs. Party members mark a target by whispering the appropriate command to the party leader. Only the party leader needs to have this mod installed.
To mark a target with a raid target icon, simply acquire the target and whisper the following command to the party leader:
[icon] can either be the name of the icon like "skull", "diamond", "cross", etc. or it can be the name of the color of the icon such as "pink", "orange", "red", etc. [icon] can also be omitted, which will use the "default" icon. The party leader can define the default icon for each party member, so many times simply whispering ".mark" will be enough.
You can configure the permissions to dictate which players can use which icons. This could be useful if you want to be able to easily tell who is marking what. The permissions are separated in to groups: Everybody, Guild Members, and individual players. All permissions are additive, meaning that if you allow guild members to mark with the skull, and allow everybody to mark with the circle, then guild members will actually be able to mark with both the skull and circle.
By default, Everybody is allowed to use all icons, so no configuration is necessary to start using this addon right out of the gate.
You can configure the default icons for each group. This will define what icon will be applied when someone simply sends .mark in a whisper. Groups lower on the list take precedence over groups higher on the list. This means that if you assign an individual a default icon, he will use it even if there is a default set for Guild Members and Everybody.
I personally recommend having your friends make a macro to whisper you the .mark command and then you can choose what icons will be used by setting the individual defaults.
Chat Commands /mark
Installing this mod also gives you access to the /mark command. If you are the party leader, /mark [icon] will mark your target with the icon you specify, or if you simply type /mark, it will mark your target with whatever default icon you assigned for your self. If you are not the party leader, then this command will send the .mark whisper command to the party leader. Be sure to check if your party leader is running Mark My Words before you start spamming them with tells!
You will also be able to use the /markmouse command to mark the mob/player that you are currently hovering your mouse over. Note that this will only work if you are the party leader. This is nothing more than an alias for "/script SetRaidTarget('mouseover',1)" with the added ability to specify the icon by name instead of just number.
