To enter the club door in Nimbus Station (by the vendor at red blocks) you need to get your membership number. you can get this by finding it on the piece of paper included with the Club Magazine, or email the Lego club and ask for it. once you have found your code, head to the Lego universe page, and click on my account. find the box saying 'add code' and click on it, sending you to a page where you need to enter codes. type in your membership code and it should allow access to the club door. once in the club, you can get exclusive gear, head to any part of the Universe from there, and get hints from the club mascot Max.
