Since there seem to be no takers, here's what I'm doing currently.

I wrote an HTML form and PERL script to send emails to the
<listname>-request at host.com address, with "subscribe" in the subject, which
seems to do the trick.  You can modify the form and script to accommodate
any number of email lists.  (Superflouous HTML formatting removed)

HTML FORM:

<form method="post" action="/cgi-bin/email_list_subscribe.pl">
Sign up for list1: <input name="list1" type="checkbox" value="list1name"
checked>
Sign up for list2: <input name="list2" type="checkbox" value="list2name"
checked>
Your Name (optional): <input type="text" name="user_name" size="40"
maxlength="100">
E-mail Address: <input type="text" name="user_email" size="40"
maxlength="100">
<input type="submit" name="doit" value="Subscribe to List1">
<input type="hidden" name="listtarget" value="subscribe">
<input type="hidden" name="acktitle" value="Thank you!<br>Your request has
been received.">
<input type="hidden" name="acktext" value="Click <a href=/>here</a> to
return to the home page.">
<input type="hidden" name="counter_file" value="subscribe_counter.txt">
</form>

PERL SCRIPT TO HANDLE IT.

#!/usr/bin/perl

$root_dir = "/www/domain";
#location of qmail-inject on your system
$mailer = '/var/qmail/bin/qmail-inject'; # If you're using sendmail,
probably change this to /usr/lib/sendmail or something like that.
$topfile="$root_dir/templates/top.html";
$bottomfile="$root_dir/templates/bottom.html";
$datapath = "$root_dir/data/list1/";
$counterpath = "$root_dir/data/list1_counters";
