sraun's method is the one I use for finding feeds, both on LJ and DW. It's at the bottom of http://www.livejournal.com/syn/ .

In this particular case: when I paste what ought to be the main tor.com feed address http://www.tor.com/feed/ into the field, it tells me there's no feed for that URL. Curiously that's the same URL that's at http://tordotcom.livejournal.com/profile (whose last status is an error message). So... I got nothin. Maybe the same kind of problem that therck mentions?
