On the site's FAQ it reads: "Games Released December 2008 and After All Nintendo DSi, Wii, and Nintendo DS games published by Nintendo in December 2008 and after can be registered and will qualify for surveys. All DSiWare, Wii Shop Channel Games, and Wii Channels released December 2008 and After will automatically be registered if you've linked your Nintendo DSi Shop account or Wii Shop Channel account to your Club Nintendo account (Post Play Surveys only)." I haven't had my DSi for long, but I've read that people did a post-play survey for the browser. A post-play survey gets you 10 coins. I think in a few weeks I'll have the browser survey. You are right in that under the coins section it doesn't mention the DSi shop at the moment. As a matter of fact, the browser survey mentions the Wii Virtual Console.
I just signed up for Club Nintendo last week when I bought my DSi. I'd just like to know if there is any news on which DSware titles offer the surveys for "coins" in the North America club. I heard that the browser will give you a 10 coin survey. Has me thinking that the 200 point games, for 10 coins, makes for a pretty good incentive if this is true. Please help if you know.
