I'm very new to WordPress and have a question about how to manage Authors.
I am looking at using WordPress as a corporate intranet news "engine", but need to know if I can allow Authors to edit only their page. Basically, as the admin, I'll create multiple pages that represent departments, and I'd like to set up WordPress to allow for a user, or users, to be assigned to each page so that they can add, edit, etc. posts to that page, and that page only.
I don't have WordPress installed, but I've played around with the demo on opensourcecms.com, but can't seem to do this. Is this possible in the default install of WordPress, and if not, how difficult would it be to do this?
