Standard Trackback system.
Download the plugin.
in config.php / after .. add
$db_trackbacks = 'sed_trackbacks';
--Before install you need to run the trackback.sql file on MySQL.
--Copy the trackback.php in your main folder. This file will be used to ping your site by the pingers, can be used: http://www.yoursite.com/trackback.php?r=1 ($r represents the page id to be pinged)
--You can see the skin files page.add.tpl and page.edit.tpl, these are specimens, edited from standard Sed-Light skin.
--Now install the plugin.
Standard Seditio core doesn't give us a lot of oppurtunities to edit (because Seditio is not a blog), but will be improved later.
#4. Known issues
This is not a bug, but if you try to trackback your site (eg. your site is yoursite.com and you use http://www.yoursite.com/trackback.php?r=1 from your server) it will trackback the url but will not add to the list.
