Which news servers (and versions) were tested? It should be documented in the early archives of this list. Here is a typical Path for an article that reached news.dotsrc.org: Path: news.sunsite.dk!dotsrc.org!news.szn.dk!news.bunk.cc!pnx.dk! newsfeed101.telia.com!nf02.dk.telia.net!news.tele.dk! feed118.news.tele.dk!not-for-mail It is really a question of whether a server has it in its active file. If so, then there is no reason why it should not pass straight through it. The flooding algorithm will, as usual, find a way around any servers that don't participate, but is will simply be a configuration affair rather than any failure of implementation. The real difficulty will be in user agents. I can read the danish group in Opera, but for some reason it doesn't like yours. Ensuring there is a working Path between your server and news.dotsrc.org might be worth a try. >> Some early USEFOR drafts show how the Newsgroups header was to be >> extended.
