I'm afraid your answer lacks the necessary contextual structure for me to give a definitive answer.
In other words; I don't understand your answer. How to be an official club.
Does this mean you want to set up an official twilight club? If so, then give up no, I'm afraid. To be official, you need to be an official in the twilight world. (I.e; You need to work with the film, or the books).
I hope I didn't come across as harsh, as that is the last thing I tried to do.
