First, I would not encourage re-registering for people who can not remember their password. This causes duplicate entries for the same person and most times the system will not allow you to register again with the same email address.
There is a page when you login to send you your password via email on the login page. You must be logged out to see this page.
http://www.landracing.com/forum/index.php?action=reminderThis sends you a temp password to get into the system under your username, then the user must go into his profile and setup a new password of his choosing.
Now there is a situation when you have forgotten your password AND you have changed email addresses which sending it to that email does NO good. So its important that you regularly check your profile information and make sure its up to date.
SSS can reset your password for you, but this should be a LAST resort, all other avenues should be done first before emailing the administrator... I have emailed SSS the procedure for this.
