Ok, not really. But it's way for Mongoose to show its appreciation to us (the custoemrs) by sending us free downloads of support material. If you do a search on them through thte forum, it'll tell you how to join. If you cut out a small corner of your rulebook & send it to them, you're in. They'll begin to send you the new material as it's released. In theory, those of us who were late joiners will at some point receive the old stuff as well. Also, they'll send you a coupon for a % off the 2nd edition rulebook when it is finally released.
