Your saying 'scam aside' is inappropriate. The whole thing is a scam. A
very successful one, too. It's been going on for about thirty years.
Ordinarily, a person can set up an account and have the cheque deposited in
it. I would stear clear of anybody asking me to cash a cheque for them,
especially from Nigeria. There are so many sob stories going around the net
and it's tempting to give the writers of them a hand. Unfortunately, the
majority are scammers.
If you can, borrow or buy the book The Big Sell by Pierre Berton. Though it
was written in 1963, the advice in it is still applicable and remarkably
relevant. I must admit that I've fallen for many of the tricks that Pierre
Berton warned about. If I was a school teacher, I would insist that my
students read the book. This is one book that deserves to be read by
Bruce Atchison - author of Deliverance from Jericho (Six Years in a Blind
School) and When a Man Loves a Rabbit ((Learning and Living With Bunnies).
