What i want to do is:
1. Given the names in the array, assign a random 4 digit number to each one (which i could do with a hash).
2. Print out that full list of names and numbers
3. Print out that list of names and numbers but without the first element Greg
4. Print out that list of names and numbers but without the second element Caroline
5. Do that for the whole array.
Eventually, i will get round to emailing each person in the array, a list without the their name and number in, so as they dont know what it is.
Hope that is clearer
