Hi,
I made this account about 2 years ago, back when this game was just getting off the ground, and I never really did much with it. :P
Now since then, I've started using a different username besides Blode4 on multiple sites and was wondering if I could delete this account in order to start a new one, or perhaps just change my username.
No you cannot delete nor change usernames. You can only create a new account.
Is there any way I can keep the same email when creating a new account?
I wouldn't think so, since you can't delete accounts and the email you used to register is still tied to your current account. If you wanted a new account you'd need to make a new email.
