Personal this post may seem pointless, but it helps a lot when you're in need of a dg or free up space in the inventory.
Just do the following:
Press ç to open the mail.
then click send.
Then comes the secret. Suppose your nick name es'ta well;
(XxxxXxxxX.) Note that contains uppercase and lowercase characters.
You just need to type in all uppercase or all lowercase (xxxxxxxxx) that mail comes to yourself. without having to log out and another char.
I know it's very simple ma post helps a lot in dgs.
Sorry for the english, I used Goolge translator.
