If you like to read other people's email, especially people that work in large corporations, this is the place for you. Look for a link "Search iCONECT 24/7" about halfway down the page, then choose Enron Email from the limited selection of searches. The interface is not obvious, but you can search on any word, then view a list of the emails (I suggest using the Set Table View Options button to customize the returned list to show only subject, title, etc.) Some 200K individual emails from Enron employees are available. The social security numbers have been vetted, but the spam and jokes, triviality and fraud of thousands of lives lived before the heart plug was pulled on the company that gouged me for a few thousand in gas and electricity bills, and helped show Gray Davis the door, are there for everyone to view.
p.s. in case you think your email at work is private, it is not.
