Editing Trackback (section)

==Function==
A trackback is an acknowledgment. This acknowledgment is sent via a network signal ([[XML-RPC]] [[Ping (blogging)|ping]]) from the originating site to the receiving site. The receptor often publishes a link back to the originator indicating its worthiness.  Trackback requires both sites to be trackback-enabled in order to establish this communication.

Trackbacks are used primarily to facilitate communication between [[blog]]s; if a blogger writes a new entry commenting on, or referring to, an entry found at another blog, and both [[Weblog software|blogging tools]] support the TrackBack protocol, then the commenting blogger can notify the other blog with a "TrackBack [[Ping (blogging)|ping]]"; the receiving blog will typically display summaries of, and links to, all the commenting entries below the original entry. This allows for conversations spanning several blogs that readers can easily follow.
