Please accept my apologies for passing on scams, dressed as warnings about scams. This load of old cobblers arrived on my work e mail and they have 5 aggressive maladjusted techies working feverishly to keep things nice and tidy, so I just accepted it and now look foolish.
I thank you jOhn for the telephone preference advice - I am signed up, so perhaps this thread wasn't a waste of bandwidth. I'll beleive anything me - which might be a good thing. If I had thought my very own personal plea from the Widow of ex-King Ngarro of Nigeria was a con, I'd have very likely missed out on me 20% of a veritable shit-load of money.
