There should be no presumption that your email is private. Email security is lax, at best. Passwords can be guessed. Messages can easily be printed or forwarded to others without considering the content of messages. Do yourself a large favor and reserve your most critical comments for your journal.
Web links Another casualty of recent litigation is the linking of one web site to another.
There have been several recent cases in which employees were reprimanded or fired because they linked their company web site to their personal web site. Their web sites contained information which some people considered offensive. These people then complained to the company for supporting such information, even remotely. The best advice is to never link your personal and professional web sites. You must also be careful if you are part of your company's web design or management team.
