Ok, I just found out about Club Nintendo so today I also figured out you could link your Club Nintendo account to the Wii Shop Channel. I bought many WiiWare games and channels, but would Club Nintendo add coins for previous downloads before knowing that you could link your account to the Wii?
If you don't understand what I mean, just comment it and I'll say it again.

Unfortunately, no. It will no record previously downloaded games. It will only register games purchased AFTER you link your account.
