Many people assume that everything posted on the Internet is public domain, probably because our law used to protect published works only if they displayed the proper copyright notice upon publication. The law, however, has changed: neither publication nor a notice of any kind is required to protect works today. Simply putting the pen to the paper or in the electronic medium, putting the fingers to the keyboard creates a copyrighted work. Once expression is committed to a tangible medium (and computer media is considered tangible), copyright protection is automatic. http://www.utsystem.edu/ogc/intellectualproperty/useofnet.htm
The bottom line is: Protect Yourself and Respect Others .
