From Red Pill Media:
RPM's Mail Whale is a kiosk application designed to assist in the collection of e-mail addresses for mailing lists. This program is ideal for lectures, tradeshows, retail environments, night clubs, or any sort of venue that a computer can be left unattended. This program does not require an Internet connection so you can take it anywhere you can take a computer. Never translate addresses again and have a new and innovative way for your customers to sign up for your mailing list. Watch your mailing list fill up with clear, accurate, database ready e-mail addresses. Mail Whale is easy to use and customizable to fit your needs. You can even run a contest or set up a rotating display of messages. Mail Whale keeps log files to let you know how many addresses you've collected, on what dates and venues, and even keeps a list of your contest winners.
