Hi Jozsef. Another great build from this set :D. To answer your question – The group is for people like you (and me) that build alternates from a Creator set. Go to the group home page. On the right hand side click ‘Join Group’. Then go to ‘creations’ on the right hand side click ‘Add your own’. Select the ones you want to add. I suggest to add a few (your favourites) not all. Welcome to Mocpages. I look forward to your future creations.
