How to configurate permissions
(housekeeping)
Permissions allow us to set the number of authors and readers of a blog. That is, if we want our blog to read only certain people choose "Only people I choose", or "Only blog authors". If we want to add authors, click on the button "Add Authors" and add the user (email account) that we want that, as well, will be the author of our blog. By entering this page, the authors and readers of the blog are listed. This section has the same philosophy as GoogleDocs. Blogger identifies, when necessary, to the authors and readers of the blog. Then, the navigation is redirected to the web page where you have to enter your username and password. Thus, the blog will be shown or not; and you will be able to write on it or not.
