rails- feet shoulder width apart (wide), lean forward NOT back, keep your eyes on the end of the rail
(frontside) 270 out- do the above but keep your shoulders square with the end of the rail (facing more forward than you might normally) and grip the rail with your feet by ever so gently dipping your back toe down and your front toe up, and right before the end of the rail hop into the 270 out. only need to worry about your feet getting the rotation really
Theres a whole wealth of knowledge on there. Everything from how to slide a rail, to grab names, to how to stomp your first cork 7s. Every time you have a question, check there first, that way you can avoid getting berated and karma raped for making a repost thread.
