my brother has an account on mt a long time ago it still exist but the problem is he can,t gain access to it because he forgot his password. it is possible to regain it?

I'm guessing that a forgot password function will be implemented in Minitokyo v3, like something you would see when signing in to Yahoo or MSN. As of right now, until Minitokyo v3 is executed, the only way you would be able to help your brother out is by sending a Support Inquiry to the moderators.
