Hello:
I would like to begin the process of becoming ATC for KSDF.  I clicked on the "Start the Process" link on the Vatusa home page and entered my Vatsim pilot ID number and password.  I was rejected with all red letters stating that I am not a controller, which I realize.  There seems to be some interchange between pilot and controller credentials.  Is there a separate Id and password for logging in as a controller?  Thanks.
