A new one to me.

Dear ************
Thanks For Your Prompt Response.
All You Need To Do Is Just Simply Go To Any Moneygram Agent In Your Area,Make A Transaction Of Lets Say $2,000 To Yourself Also. Just Like This;

Sender's Name ------- ************
Receiver's Name-------************
AMOUNT SENT----------$2000

Since Both Sender And Receiver Is Your Name,You Are The Only One To Cash The Money.All You Need To Do Then Is Just Give Me The 8-DIGIT control/reference Number.
With This Reference Number,I Will Use My IP HOST Here In London To Inflate The $2,000[two thousand Dollars] Into $20,000[Twenty Thousand Dollars].
When This Is Done,Then I Will Inform You Immediately So That You Will Go To Another Moneygram Outlet And Cash The $20,000 Still With The Informations You Used.All You Need To Do Is To Write $20,000 On The Column For Cash Expected.
I Used $2,000 As An Example,If You Can Make It $5,000,We Will Cash $50,000 In Another Location.
And With $50,000 In Our Hands,You Can Travel To Lets Say California Or Tenneessee Or Any Other State And Repeat This Transaction As Much As We Can Go And Before You Know It,We Will Be Having Over $1,000,000:00 To Share.
Kindly Do This And Get Back To Me Soonest
Regards

The 8 digit number is enough for the scammer to withdraw the $2000. There's no reason to think the scammer works for Moneygram or can do what he says he can.
