By default, WordPress (2.5 and later) comes with two RSS feed sections on the Dashboard. You can customize these by clicking the “Edit” link and typing in your own RSS feed URL.

But what if you want to add more than 2 feeds to your dashboard?

Just use the free RSS Mix service: enter in the multiple feed URLs that you would like to syndicate in one of your WordPress Dashboard boxes, and then click “Create” to join those feeds into one new feed that you can enter into your Dashboard.

One disadvantage to this tactic is that you have to create a new feed every time you want to edit the list. But still, this could be helpful for WordPress bloggers who would find other sources of information (besides those related to WordPress) more relevant for their blog’s “administration homepage.”

Have you ever noticed all that stuff cluttering the footer of many website feeds these days? As more and more traffic is converted to RSS subscribers, many blogs are slowly moving some of their advertising, affilliate links, and promotions to their RSS feed. Others prefer to use this space for other things, such as promoting certain pages or archives on their blogs, or even adding a copyright notice to their feed in hopes of warding off content theft.

Have you ever wondered how to do this? Odds are, if its something you want to be able to do with WordPress, someone has probably made a plugin that does it. Doing this is no exception, as WordPress users have access to a couple wonderful plugins to help them easily accomplish adding things to the footer of their feed.

Of the few available, my personal favorite is the Feed Footer plugin. This plugin allows WordPress bloggers to place whatever they want in their RSS feed, and then use HTML to format it to look how they want.

Unfortunately, many bloggers fail to randomize their promotions, which can often cause a form of ad “blindness.” This plugin also helps users to avoid this problem by allowing you to enter up to 10 different feed footers. It will then randomize them so each post has something different in the footer from the last one.

If it doesn’t sound like Feed Footer is for you, there is another plugin that has gained a lot of popularity called RSS Feed Signature (formerly known as Sig 2 Feed). Last I checked, this plugin allows you to place just about anything you want below your feed, however, I don’t believe it supports post randomization.
