[quote name='Ultimatallica']LOL, you'd have more success just typing in random numbers.[/quote]
I'm not sure about that....I just entered two codes, they are ten digits, and can include numbers and letters. If any space can be a letter or a number, and we can repeat digits/letters [which it looks like they can], assuming I did my permutation correctly [which I might not have], there are about 922393263052800 possible permutations. [Feel free to correct me, anyone--my memory is way foggy on combinations and permutations]. Not all are valid, and some that get entered someone else might have already claimed.
Oh, and you don't actually have to keep the caps--you can, to be on the safe side, but once the code is entered and accepted, it voids out the cap.
