It has details about all the free games that I know of, plus a paragraph each on a bunch of commercial games, plus a list of all PBM Games on the planet courtesy of Flagship Magazine. The PBM List is also posted to rec.games.pbm once a month. Yes, the PBEM Fanzine is available by email or other means, and has articles about all sorts of free PBEM games. There has been at least one false start on an e-magazine covering all sorts of PBM games. The biggest problem is probably a dearth of articles.
Back issues are at the ftp sites.
There is a way to use ftp via email. I read German or Russian or Italian. There is a newsgroup de.alt.games.pbem with some interesting things going on, but it's all in German. Likewise, there is a newsgroup relcom.games.pbem, which is mostly in Russian. Usenet is traditionally a non-commercial place, because many people who read the Net are actually paying to receive articles.
