A Problem With Scrap Blog

if I'm working on scrap blog at the same time as Laura and my page 2 is blank and her page 1 is blank and if Laura publishes last then the page 1 will become blank because it over-rides. as sir suggested we are going to have 2 separate scrap blogs with the one account and have a page full of links which link to pages on one person's scrap blog and the partner's scrap blog as well.
