Please go to your account page and make sure that the email address you've entered in your account is NOT your dropzone.com email address. If you forget your password (and the answer to your security question) your new temporary password will be sent to the email address on your account. And of course, if you forgot your password then you won't be able to get to your dropzone.com mail to pick up your new temporary password!
Your account email address (unlike your forum profile address) is not shown anywhere on the site. Go update it now. I will not fix your email address though the back-end systems so if you leave a dropzone.com adddress there you do so at the risk of locking yourself out of your account.
