I just logged in and converted my "My Nintendo" membership into "Club Nintendo" membership. It recognized 4 games and 1 Wiiware title that I had previously registered, and then allowed me to take a survey for each game. The surveys were pretty vague but after I was all finished I already have 210 coins. The biggest beef I've had since the beginning of my Wii experience is the fact that only Nintendo-brand games like Mario, Zelda, etc qualify to be registered. The dozen or so other games I've bought did not qualify, and there's not a good way to tell before hand if a game will qualify. I remember at the very beginning they advertised some deal like "register 5 games and get a free prize" however I could not find 5 games being sold that would qualify (this was like around 6 months after the Wii was released).
