Actually, I have an idea. To prevent people from voting the "most voted theme", I think members shouldn't be able to see what's in the lead until the voting is over. Just an idea though. Don't get angry at me.
You can take screenshots in-game by pressing f2 or fn+f2. To view your screenshots, press shift+command+G and type ~/Library/Application Support/minecraft/screenshots.
Not to complain, but I sometimes wonder how interesting skin contests would be if we let the mods/best skinners decide what theme we should have. Plz don hate on meh. D:
