Notas do Editor

  1. Go through these procedures fairly quickly: there’s an exercise to learn this You want them to be able to understand the form and what it says. DOMAIN APPROPRIATE FOR THE CONTENT: Do you trust a NYT times article from a personal page as much as one from nytimes.com? A copy of Jackie Onassis’s will from a personal page as much as one from the California Bar Assn.? Example of a personal page would be: www.aol.com/~jbarker They are loosely paralleled by the sequence of the form in the next exercise.
  2. You can trust the lii.org more than many referrals. If there are annotations by professionals, that helps. The burden is on you, always. Demonstrate link: search example in Google. Use http://www.hanksville.org/yucatan/mayacal.html
