Just noticed that this was released the other day:
The standalone TrackBack implementation is now released. This tool allows anyone with a server capable of running CGI scripts to send and receive TrackBack pings, and display those pings on their public site. Instructions for integration with other content management systems are included in the documentation. It is also a good reference point for any other tool developers interested in integrating TrackBack into their own systems.
(Note: I’m doing little or no blogging this weekend. Back in force Tuesday.)
