I just remembered how much I used to play diablo.. Is there any way I can recover my account or something? I hardly remember the username let alone the passwords..

Also, im pretty sure after 3 months your acc would get deleted or something..?

After three months the account is gone and there is no possible way to recover it. Try making a new account with your old account name and if it works then you know it was deleted. If it has not been three months and you registered it with an email address you can recover it with that. If you did not register it with an email address you cannot recover it.

can contact blizzard and ask them to send information to your EMAIL that was registered with the account, (if you ever registered one)

Dice d3 is coming out all accounts tht hav expired just click and u can play to get a account back just contact though diablo by email
