To use this script, simply define your form with the following text:
<form method=post action="/cgi-bin/homestead/mail.pl?member_name">
where "member_name" is your GeoCities member name. You can then develop any form that you'd like to use, and get the results sent to your mailbox.

The server side form processing that geocities provides does little more
than format what is mailed to you.  Turns out that the client side
"mailto" is as effective if you use a late version of Netscape or the
freebie formatter program.  What "real" cgi support on the server would
allow is the ability (for example) to update a database on the basis of
the form information supplied, or to query a database and supply the
user with a response based on his request.  Geocities doesn't support
that kind of cgi because of the security problems it can cause.  And I
don't want to have to learn another programming language in order to
support the concept on a site that is less rigid than geo. . . What is 
important is that people understand what can be done with cgi, 
if they are willing to expend the effort.
