I am receiving messages that ITB users are getting the automated email to advise that they have ITB messages in their inbox and when they check there are no new messages.
You can disable this automated email by selecting "my account" "edit" scroll down page to "Private message settings" and uncheck the box for the automatic notification.
ps. As pointed out in a comment, and I can confirm this, a number of users are registered with more than one user name on the same email address and this would account for the automated message if you are not checking the other user name(s) inbox. If you wish duplicated accounts to be deleted, please advise me.

In The Buff is a community site, which aims to promote the naturist cause. Members are a friendly community of natursts, that enjoy practising naturism either at home, on the beach, on holiday, or anywhere the fancy takes them. They may have been naturists for a week, a year, or their whole life. What brings all the naturists here together is the fun and friendship.
