Man... if the people knew The World was so dangerous..

If rumors did spread out, then Tsukasa would be bombarded by emails.

Probably with messages like "OMG! U R TEH LIER!!!!!!111!!" and "OMG! HWO R U NT LOGING OUT?????"

I think it was for the best that no one except the main characters really knew that he couldn't log out. But that brings up another point, he could only be emailed if they knew his email, and that usually requires a member address...and he doesn't give out his member address freely...

well, email isn't the only way to talk to someone. Eventually, Tsukasa might come to a root town where people would recognize him in the event that rumors spread out.
