4. Other settings can be changed via the Interface Options
Skinner has 2 main sub-directories; AddonSkins and SkinMe.
The skins for the Blizzard UI are in the 'core' set of files.
All the skins for individual Addons are in the AddonSkins directory and the SkinMe directory is empty, apart from a placeholder file
To skin an Addon copy/move the file with the matching name from the AddonSkins directory into the SkinMe directory.
To unskin a skinned Addon, remove its file from the SkinMe directory.
These changes will only come into effect after WoW is restarted not just reloaded.
All the files from the AddonSkins directory can be put into the SkinMe directory with no detrimental effect. If you don't have the Addon loaded then the skinning code will be removed from Skinner's memorypool.
