From the front page, click on “register” in the upper right hand corner. Enter a username, your email address, and create a password. Once you have submitted that information, you will be asked to create a user account by entering some additional information. To create a working account, you need to fill in the required fields marked with a red asterisk.

A confirmation email will be sent to the address you entered. To activate your account, you need to visit the link in the confirmation email and enter your password again. Once this is done, you are a fully registered user and can add comments and data to the map.
