I just registered on this site this evening after the Windows aps release announcement.
I've been a gmail user for about a year and a half, and this is the first time gmail has classified as spam something I hope was not.
I clicked the "not spam" button. If more of us do this, perhas the classification will get changed.
Simon, this had better not be a spam scheme. But I don't think it is. Way too much work on the back story, and way too narrow an audience for most spam schemes.
