WordPress users who wants to use other sources of information on his admistrative home then they need to use more than 2 RSS Feeds into your blog admin section. For that they have to perform these steps:
-> Open this URL: http://www.rssmix.com/
-> Use this free service and enter in the multiple feed URLs that you would like to syndicate in one of your WordPress Dashboard boxes.
-> Click on create to join those feeds into one new feed that you can enter into your Dashboard.
Disadvantage of this tactic is that you have to create a new feed every time you want to edit the list. But still this is helpful for WordPress users who find other sources of information besides related to WordPress more relevant for their blog’s “administration homepage.”
