==========================================================================


Kala Forum digests (back issues) and other miscellaneous Kala
documents are now available through ftp from 

                            =============
                            world.std.com
                            =============

To connect to this ftp site, type the following at your Unix shell
prompt:

    % ftp world.std.com

or consult with your system administrator if you use any other means
for accessing the network (such as BBSs, CompuServe, etc.).

If coming through a regular Unix connection, you should see something
similar to the following:

    Connected to world.std.com
    220 world FTP server (Version 6.12 Sat Nov 7 22:18:34 EST 1992) ready.
    Name (world.std.com:your_name): anonymous

You must enter 'anonymous' at the Name: prompt. In response, you will
see the following:

    331 Guest login ok, send e-mail address as password.
    Password: 

Next, to be on the safe side, type at the ftp> prompt:

    ftp> bin

On the world.std.com computer, the publicly accessible Kala documents
are located in the pub/kala directory. Change your current working
directory to it using:

    ftp> cd pub/kala

The Kala public materials are organized into the following few
subdirectories:

    pub/kala
            /KalaForum          -- contains all back issues of the
                                   Kala Forum digests
            /Articles           -- contains preliminary versions of
                                   articles published elsewhere
            /ShortDocuments     -- contains various technical and
                                   business documents about Kala

To get at any of these directories, just type 'cd directory-name' at
the ftp> prompt. To list the files in the directory you're in, just
type 'ls' at the ftp> prompt. To download any of the files, type:

    ftp> get filename

To exit ftp, type 'quit' at the ftp> prompt.

All Kala Forum issues are in ASCII text only. Other documents have
names ending in '.txt' to indicated that they are in ASCII text format
or '.ps' for PostScript format (other formats later).

Please let us know if you have any problems. Enjoy!
