Im sorry but i will not accept this kind of event anymore.
If you wish to give your account to somebody its entirely your choice but you need to do it privately and i can not support you in this and i can not allow it to become an event because accounts , passwords , characters , and any other belongings if yours in Mornia Mu Online are PRIVATE .
In order to change your email address you need to follow this guide :
[Guide]Email Reset
I would suggest you would keep the account for yourself in case you return , however what you want to do with it is your decision and your responsibility.
All the best.
