Application essay! Any specifics on how to format, head, title, space, etc?

<p>Hi once again! :) I was wondering how an application essay should be formatted. The consensus seems to be that as long as it looks good, it'll work. BUT is there anything you would suggest? Should it be double or single spaced? Header, footer? Should I include the topic, my name, class year? If so, where?
If this makes a difference, the essasy is being submitted in a space on the online application.
Thanks guys!! :)</p>
