If you like the Feedburner Headline Animator, but did not use it because it failed to blend with you email or forum signature, the new feedburner email signature will be useful
This is how my feedburner signature now looks like
The Animator is a dynamically generated graphic that fades between the text of 5 most recent items in a publisher’s FeedBurner feed. Publishers who sign up with FeedBurner to republish their XML feeds can get this graphic uniquely generated for each feed they set up in their account.
If you already use a Feedburner feed (I recommend you do), then after logging in, click Headline Animator on the menu of publicity services on the left hand side of the page, enter a title for your Animator on the preview form that appears, click Activate and you are done.
