integrating usenet into http? how is this done???

Hi guys, I just found a site where they have integrated a usenet forum into their own forum. I am wondering how this is technicaly done? The postings seem to be pretty up to date ( I did compare them with the usenet ones) Here is the link: http://britishexpats.com/forums/forumdisplay.php?forumid=43&s=e80f5f41207018 c5dd5751801faf1037 Has anybody an idea how they do this. I think the forum software is phpbb. But they do not provide such a function as far as I know. All the data inside phpbb comes out of a db usually. How is this done with copyrights anyway? Andy
