There are a number of members who have not updated their profiles from the null email address. Please change it, or at least uncheck the notify of reply choice in your profiles. I unchecked the notification in the profiles of three members just now and I know there are some more. Reason I knew about the three was that I get an email showing a bounced notification every time anybody responds to anything they post.
Thanks.
Please check your email addresses
