out the email for free services. USA.NET is one vendor.<br />

Non Latin characters<br />

"Foreign" characters, they call it in some places. Internet experts call it Extended<br />

Character Sets. Those of us with a regularly need to write or read in other languages<br />

than English, might simply call them <strong>The</strong> Challenge.<br />

In 1982, when email was defined, the decision was made to encode email in such a<br />

way that only 128 different characters letters, numbers, punctuation, and so on could<br />

be transmitted from one computer to another. We are still suffering from this decision! It<br />

means that many people have difficulty sending and receiving mails containing<br />

characters like ‰, Á, and ÿ, to mention a few.<br />

<strong>The</strong> good news is that there is a way of encoding data so that 256 different<br />

characters can be represented, called "quoted printable".<br />

<strong>The</strong> bad news is that the underlying transport is still limited to 128 different<br />

characters, so the email gets converted to the more limited set, transmitted, then<br />

(hopefully) converted back on the other end. If the receiving software doesn't know how<br />

to do quoted printable, the extended characters will show up as an equals sign and two<br />

letter/digit code as in this Spanish language text:<br />

Ah=ED van mis saludos y mis =E1nimos para ti y para todos los = argentinos. Sigo<br />

desde hace tiempo con preocupaci=F3n lo que pasa en = vuestro pa=EDs. Me<br />

sabe mal que tengais que pasar por =E9sto y me siento = impotente, sin saber<br />

qu=E9 hacer. No perdais la esperanza ni la = confianza en un futuro mejor.<br />

Finally, even if your friends' email programs know how to convert codes back to<br />

extended characters, different computers have different symbols for the same codes. For<br />

example, the trademark symbol, bullet, and "curly" quotation marks are all legal<br />

characters in both Windows95 and MacOS, but are in different places in the character<br />

set. For example, Windows thinks that character number 241 is a Ò, while the Mac<br />

thinks that character number 241 is a “.<br />

Anonymous mail<br />

Some day, you may want to send a message anonymously. Try Hushmail, designed by<br />

hackers for total security. <strong>The</strong> mail message's headers are gone. Nobody knows where or<br />

who you are.<br />

Internet's Anonymous re mailers will also let you do that. Check<br />

http://anon.efga.org/~rlist/rlist.html for a list of servers and directions.<br />

<strong>The</strong>n, visit the alt.privacy.anon server and alt.anonymous newsgroups for more on<br />

anonymous email.<br />

Things Take Time!<br />

How long does it take a message to get from Hyougo in Japan to Saltrod in Norway? To<br />

Dominique Christian in Paris?<br />

Sometimes, mail travels from mailbox to mailbox in seconds. This is usually so with<br />

messages from my mailbox in Norway to Dan Wheeler in U.S.A. and Mike Burleigh in<br />

London.<br />

Messages that must go through many gateways may take more time. How long it<br />

takes, depends on the degree of automation in the mail systems involved, and how these<br />

systems have been connected to the global matrix of networks.<br />

Speed is high if the computers are interconnected with fixed, high capacity lines.<br />

This was not so for my mails from Oslo to Dominique in Paris. Although the Paris is<br />

relatively close, mail was routed through a system in London, and then forwarded only<br />

once a day through a dial up connection. My mails usually took at least one day to reach<br />

the destination.<br />
