Kelly's Tracking Back
Kelly is experimenting with Trackback. She picked up a Trackback URL from one of my postings and put it in the "URLs to Ping" field on her own posting. This caused my original posting to end up with a Trackback to her reply.
However, Trackback only puts a link from the original posting to the reply posting. It may be a good idea to put a link in the reply posting to the original. Like this. I did this by right-clicking on the Posted time at the bottom of her article and copying the link.
Takes practice.
