If you have not logged into NA since the forum was migrated you will need to reset you password before you can login. The direct link is http://nappyaddicts.com.au/login.php?do=lostpw
Once you have entered the current email address for your NA account an email will be sent with a link to confirm the password change.
When you click that link then you'll be sent a new password which you can use to to login.
After you're logged in you can change your password to something you remember.
If you have any problems, contact me using the contact form below.
Thanks,
Dan.
