Andy Fingerhut has established an automatic LEDA mailing list at Washington
University in St. Louis.  I include his announcement (from comp.theory)


>   From jaf@wucs1.wustl.edu (Andy Fingerhut)
>   Subject: Announcement of a mailing list for the package LEDA

>   I'm happy to announce the creation of a mailing list devoted
>   to the software package LEDA.  What is LEDA?  It is an acronym
>   for Library of Efficient Data types and Algorithms, and is described
>   a little more below.
>   
>   What is there to talk about LEDA?  Here is a list of possible topics.
>   
>   	+  Hints on using LEDA effectively.
>   	+  New data type implementations.
>   	+  New algorithm implementations.
>   	+  Low level details of the "built-in" types and algorithms.
>   	+  Mistakes in the software, preferably with corrections.
>   
>   This list of topics is not meant to be exhaustive.
>   
>   There are actually two mailing lists.  The first is called LEDA,
>   and will be unmoderated, at least until traffic warrants otherwise.
>   It will be for anyone who wants to discuss any and all of the topics
>   above.
>   
>   The other is called LEDA-ANNOUNCE, and it will contain "major"
>   announcements, such as when a new version of LEDA comes out.
>   LEDA-ANNOUNCE will be moderated by Andy Fingerhut.
>   
>   As soon as I determine how, I will set up the mailing list software
>   (listserv version 5.5) so that all messages which appear on
>   LEDA-ANNOUNCE will automatically appear on LEDA as well.
>   Therefore, those who only want major announcements need only join
>   LEDA-ANNOUNCE, and those who want every message need only join
>   LEDA.
>   
>   How does one join?  Simply send an electronic mail message to:
>   
>   listserv@dworkin.wustl.edu
>   
>   with an arbitrary subject and one of the following lines
>   as the body of the message.
>   
>   subscribe LEDA login_name@host
>   
>   	OR
>   
>   subscribe LEDA-ANNOUNCE login_name@host
>   
>   You should receive confirmation that you have been added to the
>   appropriate list not long afterwards.
>   
>   I plan to collect additional data type and algorithm implementations
>   and make them available on either an FTP site, a mail server, or both.
