David,
Welcome to the forums. OC is perfectly legal, although perhaps a daunting task without a CPL. Pay attention to the piles of documentation and don't be afraid to ask stupid questions, as they aren't stupid. It is a hellified legal minefield, so make sure you not only have any questions answered, but that you know why they were answered the way they were and you can find the cite on your own.
Again, WELCOME!
