If you have multiple people writing for your site, and you are the one publishing all the posts and pages, you'll see that your username is always displayed as the author. The ability to change post authors in WordPress is hidden by default. To change the authors for your posts do the following:
1.Go to the Edit screen of the post you want to change the author for.
2.On the top-right of your page, click on the “Screen Options” tab. A list of options will now drop down.
3. Check on the “Author” box. A new box will display on the page with the title “Author” with a drop-down box with a list of authors (user names) to chose from.
4. Select the author name from your drop-down list. If its not listed you have t add the user.
5. Click the “Publish” or “Update” button . This will save the post with the new author.
