Movable Type bloggers can now let iWalt.com know when their site has been updated. We’ve added support for the weblogs.com XML-RPC ping interface. All you have to do is make a simple modification to your Movable Type weblog’s configuration. Just go to the Preferences form and add “http://www.iwalt.com/api/” to the list of sites to notify when the blog is updated. This will send the name and url of your blog to iWalt.com automatically when the blog is updated. I’ll use the data on iWalt to show who’s been blogging recently, possibly in the Profiles section, etc.
