Steves.

I hate it when I go on a server, and almost everybody is in a Steve skin. Maybe one of you is in a Steve skin, and want everybody (Almost) to have the same skin as you. I worked out how to mask Steve skins any skin you like. Go into Library, Application Support, Minecraft, Bin. Now heres the tricky part. Rename minecraft.jar to minecraft.zip. Then double click on your new minecraft.zip to get a folder called minecraft. Rename that folder minecraft.jar, get rid of your minecraft.zip, and go into your minecraft.jar. Then scroll down all the way to mobs. Then find char.png. Copy and paste the skin you want all the Steves to have into mobs, and rename it char.png. Then delete the old one. When you go on a server, you should see lots of people in the skin you chose!!! :D
