Hockey-L does show up in some lists of Internet sources.  I just bought
_The Internet Directory_ and it lists Hockey-L, with a entry in the index
both under hockey and under Hockey-L.  This directory is a great source
for finding out all kinds of discussion groups, anonymous ftp sources,
gophers, Usenet groups, etc.
 
As more people have access to this kind of directory, some of them will
join Hockey-L.
 
What I'd really like to see is an article in _The Hockey News_ about
internet sources of hockey news and discussion.
