I’ve had a few questions lately about how to create a service such as KMPings in MovableType. The basics are pretty simple:
1. Set up a category in MT and enable Trackback pings. Note the Trackback URL that should be used to ping the category.
2. Put the code below into an index template in the MT template library. Edit the category name to match the one you want to use. Only index pages update on ping so you have to do this to show a current listing without manually rebuilding the site.
3. Publish the url that people should use to ping the category.
