I want to make a blog pinging site like weblogs.com so when a blogger (using blogger or MT or Wordpress) hit's the SUBMIT button to Publish their blog, the blog automatically gets sent to the ping list. I know that MT has a place where you can list servers to ping but how do I get the information once the ping is sent to my server? I plan on doing this in PHP.
It is a post, of an xml document... so you would parse it and act on it. See http://www.xmlrpc.com/weblogsCom
