Next, the CPYNET code was incorporated into SNDMSG. It remained to provide a way to distinguish local mail from network mail. I chose to append an at sign and the host name to the user’s (login) name. I am frequently asked why I chose the at sign, but the at sign just makes sense. The purpose of the at sign (in English) was to indicate a unit price (for example, 10 items @ $1.95). I used the at sign to indicate that the user was “at” some other host rather than being local.
The species Torquigener albomaculosus was described by David Attenborough as “the greatest artist of the animal kingdom” due to the males’ unique habit of wooing females by creating nests in sand composed of complex geometric designs.
