I ought to get out more, or read less murder fiction. PM I interpreted as Post Mortem. Why anyone would put that sort of picture on here is beyond me, but.......
As far as I can see, there is not even the ability to 'Paste' anything into a PM. As most of us use aliases so we can't be identified, perhaps that's the reason for not being able to include anything too personal such as a photo.
Well, you wouldn't want some pervy old bloke sending you an explicit photo of a part of his anatomy via PM would you?
Some GN members have been the recipients of unwelcome advances in the past - anyone in the world can read GN, don't forget, and only has to join to send a PM.
