If you need a rule book, I would propose that the SST download henceforth cease to be refered to as 'rules', and instead be known as: 'the unfininshed playtest army lists from war of the species'.
If you want to see something approaching the old SST forum, I heartily recomend the link in my signiature, we were trying to get the word out through here, but temper got frayed at some point, and our thread on these forums was deleted...
