How to setup a Blog in Magento
 

It is not hard to setup a blog in Magento. However you should take into account that blog functionality is not included by default and you need to use a custom extension for it. You can search Magento Connect for an extension that will fully suit your needs.
One of the popular free extensions that you can use is the Magento Blog – Community Edition.
All Magento extensions are installed in a similar way that is thoroughly explained in our Magento Connect Tutorial. In order to install the Magento Blog extension get the extension key and enter it in Magento Connect for your website.
After the installation you will have one additional section in the Magento administrative area top menu called Blog. From there you can adjust the newly installed Blog settings, add posts etc.
NB: If you get access denied when trying to access the blog extension for the first time after installation try to log out of the Magento administrative area and then log back in. This should rectify the issue.
