Wordpress is a great content management system, much better than other web softwares of its kind available on the Internet. One of its great feature is the ability to have multi authors on a single blog. Previously the concept of multi authorship was not so popular and earlier content management systems did not support this idea. However, Wordpress gives us the ease to have as many authors as we desire on a blog.

All authors in Wordpress are treated as individual entities and their posts, comments, custom fields and categories are tracked along with them.

Usually when you transfer your blog you backup and export your MySQL database because it stores the data of all your posts, comments etc but what if you want to export the data of a particular author only?

This type of situation arises when an author plans to leave a multi authored blog (in order to start a new blog independently) and wants his share of posts. We can easily export the posts, comments, categories and custom fields data of that author using the Export feature of Wordpress which is often overlooked.

To export the posts of a particular author go to your Wordpress Admin Panel and navigate to Manage > Export. There you can choose the author and all posts, comments, categories etc of that author will be exported to your PC in XML format.

Now to Import this data to a new blog just follow the steps:

1. Log into that blog as an administrator.
2. Go to Manage > Import in the blog’s admin.
3. Choose “WordPress” from the list of importers.
4. Upload this file using the form provided on that page.
5. You will first be asked to map the authors in this export file to users on the blog. For each author, you may choose to map an existing user on the blog or to create a new user.
6. WordPress will then import each of the posts, comments, and categories contained in this file onto your blog.

This method can also be used to backup your blog without messing with the database.
