AHC Mailing List V.1.0
This script allows you to collect email addresses from your visitors, then you can send
out news-letters or announcements to all of your members in the database. This
script will check if an email address is already in the database before adding it in.
Also, a member can unsubscribe directly from your website if he or she doesn't want
to be on your list anymore.
