Hi -- I'm pretty new to lists (as the following question will
probably make obvious):  Recently, a dozen or so people asked me to
send the same file, which I did at considerable expense of time,
"manually".  But it is my understanding that there is a way to "post"
a file at some central location, from which anyone who so wishes can
request the file.
     Could someone please explain how this is done, or refer me to
documentation that explains same?  Thanks!            --Tom
