I dont believe anything on the internet is private. I know work emails are not private, and I believe the disboards is part of the vb systems, in which the owners, webmasters, et el do have access to PM's -
I thought this was common knowledge on any message board... back with my first message board ivillage - it was known that pm's werent "private" but not all the moderators had access to PM's, just a 'select" few...
