Most worldwide telecommunications laws and regulations require that sites that are not strictly private or personal should have a legal-proof page containing legal information. The sites that need to adapt include blogs and sites that contain journalistic texts.
The name of the person responsible for the contents must be indicated on the page, together with the address and other contact information. For example a phone number or an email address. Other information may also be needed. Consult an expert to make sure what information should be contained on your site.
