lol, i can help, but can u narrow the question, i mean, i wrote a 1500 word essay on this, actually, i may have posted that essay as a resource, i dont know, coz i got full marks...........
*runs and looks in resources*
Nup, i'll have to get it back off my friend, coz i have the essay, but its a slightly different q to yours, then ill b able 2 help ya!
But if u can narrrow ur question down to what u specifically need to know - such as resources, paragraphs, main points etc. that would b a help
