Make up your own system, you can do letter pairs which I think that site goes over. You can just memorize the patterns/sequences visually. You can really do just whatever works for you. But don't worry about memorization right now, you don't even know a full method yet and so you don't even know what memorizing a cube entails. Just learn the method, memorization should be your last concern.
wow, way to shoot me down right there

lol

umm so if someone had a photographic memory they could just memorize the cube and do fridrich with their eyes closed?
You don't necessarily need a photographic memory, although it would help. There are many people that actually do that you know... its called speed BLD.
btw I wasn't trying to shoot you down, I was being honest. Memo is probably easier than you would think, but you wouldn't know that yet because you haven't learned a method. I was just giving a reason as to why you shouldn't worry about it yet.
