What is not entirely clear to me is: the attached PDF says that if I don't exclude myself (opt out) by mailing a signed letter, I won't be able to "sue, continue to sue, or be part of any other lawsuit against Google relating to the subject matter of this case". Does that mean that, if I don't opt out, I won't be legally protected from click fraud in the future?

If so, I think I will opt out: I guess I'm not anywhere close to being a medium-to-big AdWords spender, plus I don't believe I've been a victim of click fraud so far.
