Well, in all fairness, you will just have to make an educated guess as to whether you will use it or not based on the list of what you get. Asking if its worth the money will probably get differant answers from differant people. I would say that the members database and full access to the forums are worth it alone – which is why I will join. But others might disagree.
So at the end of the day you will just have to decide if its worth it yourself and pay for it or not.
