[2017 Feb 15] New User Authentication
A new user authentication system is being implemented as of February 15, 2017. There is a new registration page and registration now requires email confirmation. The password reset function has been fixed using an email process to do the reset. You'll see these in the user login page. The registration form now has a comment box to request specific functionality such as PIREP submit. If you want these capabilities, note it in the comment box and AWC will accept or reject the request based on the user requirements for each page. The user settings page has been restored. Previously, it was only available for those users who had gone through the registration process and had a valid login. Now the favorites bar is available for non-registered users. Go under User Settings to create your own favorites bar. This doesn't override the settings for registered users. When you log in, the favorites bar will be set to what's in your user settings.
