INSTALLATION OF THE SNOW VIKING SKIN:

-Unzip wwx.u and wwx.int into your Rune/system folder.

If the skin does not show up in your list of skins, then sdd this line under 
the [Public] section in your RuneI.int file:
Object=(Name=wwx.Darksnowviking,Class=Class,MetaClass=RuneI.RunePlayer,Description=" Snow Viking") 

That's it!
The Snow Viking skin should appear somewhere around the top of your skin menu.. 
If not, you probably did something wrong.
