Katya, a reader of this site, requested a tip on the TrackBack feature in Radio. Wikipedia says...

TrackBack is a system implemented by many blogging tools, including Movable Type and WordPress, that allows a blogger to see who has seen the original post and has written another entry concerning it. The system works by sending a 'ping' between the blogs, and therefore providing the alert.

TrackBack typically appears below a blog entry and shows a summary of what has been written on the target blog, together with a URL and the name of the blog.

UserLand added TrackBack support for Radio on August 4, 2003. You'll notice that every post on this manual has a trackback link so I can easily find out who is linking to my site. Here's how I did it.

First, I made sure my Radio is up to date.

Then, I added the TrackBack macro to my #itemTemplate.txt file. I put the word "TrackBack:" in front of the macro but you can put whatever you'd like, such as "There have been this many trackbacks to this post:"

After adding the TrackBack macro, I then visited the TrackBack prefs page and selected the top two checkboxes. Then, I scrolled to the bottom of the window and entered the following for my TrackBack link text. You can change this to whatever you'd like.

Click Submit.

That's all there is to it.
