Omar Shahine uploaded a patch for dasBlog 1.6 that allows you to utilize the NewsGator ratings system. This patch adds support for a new PermalinkUrl Macro. You can use this macro by adding:

<%permalinkUrl%> to any of your templates. To add the rating system simply edit your itemTemplate to include the following text:

Rate this post: <script src="http://www.newsgator.com/ngs/ratings.aspx?rurl=<%permalinkUrl%>"></script>
(data provided from <a href="http://www.newsgator.com">NewsGator Online</a>)
