With respect to Lauren's comments (of about a week ago) concerning CSNET reliability, let me say that in the year that I've been using CSNET, it has proven to be quite reliable. There have been several times when a host has been down or experiencing some sort of software malfunction, but I can't recall having a message (inbound or outbound) vanish without a trace. When I send a message via CSNET, I'm confident that it will either arrive at the target machine or that I'll be notified in some fashion that the message could not be delivered. On the other hand, with Usenet and uucp, just figuring out *where* to send a letter is a problem of constantly increasing complexity. Furthermore, uucp messages are prone to misadventure at nearly every exchange and in many cases, if a delivery fails, the letter gets sent back to uucp on the machine it just came from. I've been on Usenet for almost three years and I'd say that for me, the lost-without-a-trace rate of multi-hop mail is probably 20-30%. Usenet is certainly quite useful, and for established communications paths is usually reliable, but the real problem is that at a large number of sites, if a message encounters difficulty, it's probably going to land on the floor. I use CSNET for mail whenever possible and recommend that others do as well. Please note that I'm not saying that claims of CSNET mail passing into the TZ are bogus, but it has been my experience that the CSNET staff has promptly responded to the various problems that we have encountered and that as a whole, CSNET is worthy of trust. However, don't let me paint a picture that's too rosy. On the whole, I am unimpressed with what CSNET provides considering the money and manpower it apparently consumes. More specifically: I think that the annual dues as stated are somewhat high, especially for small businesses and small University departments. (Actually, that might not be a fair statement as they do consider requests for reduced prices. Question: Does anybody know what the lowest amount paid for annual dues in the Industrial and University categories are?) Secondly, while the initial mmdf software supplied to us was of good quality, it forced the use of entirely new end-user mail programs for CSNET mail. CSNET later supplied software to allow use of delivermail with mmdf, but forget to elaborate on a number of problems and curiousities caused by interfacing the two systems. While I'm here, let me say something about "Usenet Inc. == CSNET?". CSNET appears to fit most visions of Usenet Inc. except for the fact that it doesn't support news. The news support question reduces to one of cost because news can be suitably disguised as mail. The problem is that if one PhoneNet site feeds another news via an intermediate host, the news must be paid for twice. Direct PhoneNet links solve this problem as would an Arpanet host feeding a number of PhoneNet sites. Usenet and CSNET have organizational structures that are nearly opposites of each other. Does anyone really think that Usenet could be completely reorganized into Usenet Inc.? The key word there is "completely". Let's say that all but 30 sites reorganized into Usenet Inc. The 30 sites continue to operate as they have. You'd have Usenet as it was about two years ago. You'd also have CSNET and Usenet Inc. in competition. I think that the reasonable thing to do is to not junk Usenet, but rather to maintain the basic premise (no central organization), and explore ways of making it better. One final question: Why do people join CSNET? I've talked to several people at sites that alreay had Usenet access and then subsequently joined CSNET. The primary reason was: legitimate Arpanet access. Bill Mitchell whm.arizona@rand-relay (preferred!) {ihnp4,kpno,mcnc,utah-cs}!arizona!whm (the real_ TZ)
