What's Nintendo club key and what does it do?
Nintendo consoles and some games come with a little card with a unique number (key) on it. You register at Nintendo's site and enter the number to collect stars with which you can buy things.
Currently, you can't buy much more than wallpapers and ringtones, but Nintendo mentioned way back in December that you would soon be able to exchange your stars for Wii points.
I don't know where you're from, but I think the stars system is only available to people living in Europe. If you're living elsewhere, that's probably why you've not heard of them before.

Just tried again today and it went through. They must have changed something on their system.
Same here. Did think it was pretty silly to put a console key and a game key in with the package if only one of them was going to work. Glad they've sorted it out.
