I’ve tried accessing the advertising section and it says “Click here to register” but when I do, it takes me back to the main forum page, whats the script?
That forum is only open to folks who have registered on the boards, clicking on that link will allow those not registered to join. As you have already registered, you don’t need to do anything to see what’s in it. Which at the moment is very little. 
To add to what’s been said, you will need to be logged in to TN to view the driver vacancies section.
