I also received this email and was surprised to see only 58.
Not to long ago, I found I was still able to login and view my old Referspot stats. Now I can’t seem to find a working link to a login page. In the email, they asked for us to email them with any additional information we might have for them. I would have liked to email my Referspot tag as well, but can’t find it. I sure hope they go through those accounts since some of us had doubts on whether all of our players were moved to the new program successfully.
