Hi Chopa I saw you in my server today

follow what JG14 said, what happens is if you zoom in about %50 of the map you will find the click able area at the the 5 o'clock position about inch from the base it self.
once you have clicked on it (as jg14 said) there will appear a menu to the right for the plane scroll down and hit Create...be warned there is a bug where the "create" button might no hilite for about 30 seconds...just wait it will
