What you are seeing in MY VBB are the postings of those that you have as a follower/friend. For example, I have Nancy G as a follower/friend. I can see everything she posts as well as all my postings. But, this is not e-mail notices! Nestle just started private messaging (PM) this past week. In MY VBB you will see an In-box or Sent. In-box are the e-mails the VBB members sent you and Sent, are all those e-mails you sent to VBB members. Now, you can also delete your e-mails in your In-box and Sent.
I hope this explains what you are seeing under MY VBB. Also, this has always been there since the new change over from the old site!
