Most of the worldwide telecommunication laws and regulations dictate that websites that are not of a strictly private or personal nature must have a legally compliant imprint. This includes websites that contain a blog or texts of a journalistic nature.
The name of the contact person responsible for the content must be stated in the imprint, along with an address and means of contact. This means for instance a telephone number and an email address. Other legally stipulated information may be necessary. Please consult an expert to find out what specific information is required for your site.
