I can inform you that I tried the site and I would recommend you to do NOT try it. It is a FAKE . They don’t give you any material and they just said that you need to buy something else.
I have not receive any email yet, but as Sarah said, it will probably be just spam emails, garbage.
Be careful if you don’t have a virus program to protect you, I can guess that it could have even virus.
I have received one or two genuine emails - RB parenting tips. But basically, it’s just a ploy to further sell some RB parenting tips - which I DEFINITELY am not paying for - given how I was mislead!
