what I did was just turned in the aadsas by paper, not on computer (I know, the old school way). Thus I stayed within space the application alloted (10 point, single space, double spaceing between paragraphs to give a less crowded appearance, from top to bottom), which I feel gave a good hint on how long they would "like it" to be. I know on computer, they give you "a lot" more room, but in my opinion a ps is all about quality, not quantity. I agree with the previous posts that if its too long, the readers will get bored, so watch out and don't get carried away with the space the computer gives you. -good luck
