This is a guide in making people without custom skins have a skin of your choice. (This doesn't affect you. only people without custom skins)

1. Find a Skin in http://skins.tkte.ch/

2. After you found your skin of choice. Click Save (This looks like a Hard Drive with a Down Arrow)

3.After you downloaded it. Find it's directory and rename it to "char"

4. Now find your World of Minecraft Client Directory and open the folder "skin"

5. Backup the file "char" there and put recently renamed "char" in that folder

6.Open World of Minecraft client and enjoy!
