Should Groupee joined TRUSTe privacy program?

Some of my member are concern about the privacy and that why until now, i still haven't move to Groupee login yet.

I heard that many large company joined TRUSTe program, like Microsoft. I am thinking will Infopop planning to join?

I understand Infopop already have a detailed privacy statement, but I think for some general users, this type of program can help them trust the site/service more.
