Just before I hit the OK button in the sign-up window, noticed the "Terms & Conditions" link - down that document at about number 7. it goes into "I hereby accept all fees for use of this service, for signing up, etc..." ...and give CallWave the right to charge me by credit card, check, or to the phone company - maybe my Cell carrier? Sorry, no - thought this was "FREE".....hmm....
