Creating a comments feed

Create a new Index template in Movable Type with an output filename of something like comments.xml and use something like this for the template contents:

<?xml version="1.0"?>
<rss version="0.91">
  <channel>
    <title><$MTBlogName$> Recent Comments</title>
    <link><$MTBlogURL$></link>
    <description>Recent comments on the Kalsey Consulting 
                        Group weblog.</description>
    <language>en-us</language>

        <link><$MTBlogURL$></link>

Of course you’ll need to change the title, description, copyright, and email address, but you get the idea. You can also adjust how many entries are displayed and how many comments for each entry are included by altering the lastn values in the template.

You’ll also need to make sure that all MT tags are on one line. MT won’t process tags with a line break in them.
