Locking accounts and the e-mail update

Hi, guys. Have you known that you can lock your account and unlock it? Well, here's a tutorial/guide:

First step:
Go to Game Menu in the left in the screen.

Second Step:
You'll find the new green button 'Lock'. Press on it.















Now, you've locked your account. But how can you unlock it? When you lock your account (click on 'Lock' button), you'll find this:

You have to enter your password here if you want to unlock your account. If you press on 'OK' without entering your password or enter a wrong password, it'll tell you. If you have entered the correct password, it'll tell you that your account is unlocked.

Ok, have you seen this when you've logged in?

Ok, who has got the idea of the 'Lock' button? It was.. Pres. Click here to see the thread on the forum!
And read the replies in the thread. You'll see a reply from Cat.

I know Cat made the update and changed some things...
Oh, and this is a video of how to Lock your account:

Hope this has helped.. Goodbye!
