Ok, i will explain.
When used properly, trackbacks and pingbacks are an excellent way to build links and traffic to your blog, as well as building relationships with other bloggers.
The trackback is a way to notify a website when you publish an entry that references it. When you send it a trackback, a link with a short excerpt of your entry will appear on the referenced website.
Picture example:

A WordPress <-> WordPress trackback looks like this:

fan. But i think we should consider trackbacks or pingbacks between sNews sites, and even between sNews and other type of sites or blogs, like WordPress for example.
Maybe a good start point is to read the tutorial above, from that link and also to take a look to the trackback part of the WordPress script. I am also looking, but i am not a very pro programmer, but i don't want to quit never, and i was thinking that here together we can create also this very useful feature for sNews.
