I too have received this unusual email, I would think that it a scam. This is the second time I have received it and will always delete it.
I had this too, and another one from someone else (I can't remember the name) about a month ago. I've deleted them
I too have received this in my personal email, but strangely it does not appear in my SMJ inbox. Either McCarthy has now been zapped by SMJ moderators or has somehow gained access to our private email addresses.
I too have had a couple of these, one just a week or so ago.
Deleted as before.
Has he been shown the door yet?
