Summary: I Have What You Sent Last E-mail
Review: Browsers, e-mail programs, or online services turn out even E-MAIL FOR DUMMIES. But they might hit electronic snags: updates might be stored like files so channels missing updates while the computer is disconnected might freeze or lock the screen by updating with the reconnection. There might be online rush hours and waiting lines: conferencing goes faster with the less error-checking ASCII text files and slower with executable and image binary files. Computer glitches might hold up messages between different systems. There might also be a lack of privacy: employers might read messages without employees agreeing or knowing and without breaking any laws. There might even be a lack of security: Active X controls might interact with the Active X support feature in a web browser to locate and upload financial information from a computer. Messages might be intercepted while passing through multiuser and network-connected computers without firewalls and randomly selected private and public keys or pass phrases or words; or while printing to remote laser printers. Messages might not delete because they copy across computers and might end up archived on computer backup tapes. Authors John R Levine et al lead readers through the obstacle course and on to David Ebner's THE TIGHTWAD'S GUIDE TO FREE E-MAIL AND OTHER COOL INTERNET STUFF and David Wood's PROGRAMMING INTERNET E-MAIL.
