For the submission of their matching lost children with the countries and for the collection of lost artifacts in the game environment, various design features in QA were used. The QA environment embraces an internal e-mail system called Q-mail. Players can send and receive e-mails to and from other QA players through this system just like the regular e-mail; the only difference is that the use of Q-mail is limited to within the QA environment. Access terminals were scattered around the Global Village to access the Q-mail system.
