right now, yes you need 5 referrals but that will be changing soon as a dev has confirmed it will be hitting the c-store in the "very near" future. I cant find the thread for some reason that states this, my guess is with all the nerd rage that was happening about this ship going on c-store they may have removed the thread.
Ask and you shall receive. On another note, this might not be the right section for this, however I have been known to be wrong on occasion. Like that time I bet Q that he couldn't get de Lancie to play him in the series. Poor Eric Menyuk didn't even make it to that audition. That reminds me of another funny bet I made with him concerning the role of Data. If theres a lesson to any of this it's that you never bet against Q, you'll lose money and actors like Menyuk will fall into obscurity.
