"You've Got Mail" is one of the most eagerly anticipated messages in the world today, and starting Monday and lasting until May 29, the three words can also lead to valuable prizes. America Online (whose own parent, AOL Time Warner, owns PEOPLE) is launching a contest on April 30 in which mystery stars from the TV, movie, sports and music worlds will utter the phrase. Recognize the celebrity voice and you have a chance to win one of three Mazda Miata Roadsters or one of 12 trips to the 2002 Blockbuster Movie Awards in L.A., as well as a Blockbuster Value Card for 52 free movie rentals (one per week for a year). During the promo, AOL members will also be able to download their favorite celebrity voices, though one needn't be an AOL subscriber to participate in the contest. AOL members may play by going to AOL keyword "You've Got Mail," while non-subscribers may enter through www.celebrityygm.aol.com. There will also be clues available to help to identify who's talking to you. May the best ears win.
