actually I haven't. I never read the rules - sometimes it gets
  me in trouble, but usually I'm ok. Most forum rules are similar
  and I'm pretty self-regulating. Most people don't notice the
  rules until they violate them and it's pointed out to them. Then
  they're surprised. But, like the law, you posted it. You can't
  make them read and understand, but you CAN hold them to it,
  whatever their complaints are when you hold them to it.
