How do you make your blog completely private on myspace?

There are people who have it to where you try to read there blog and you can't read any of it unless your a friend. How do you get your blog to be like that?

When you write in your blog, there is Public, Preferred List, Diary and Friends Only. Set it to Diary.

EDIT: Just set it to Friends Only. If you only want certain people to view your blog, select 'Preffered List' and add certain freinds to the preffered list.
