Page "Signature block" Paragraph 1

Information usually contained in a signature block includes the poster's name, phone number and email address, along with other contact details if required, such as URLs for sites owned or favoured by the author.

A quotation is often included ( occasionally automatically generated by such tools as fortune ), or an ASCII art picture.

Strict rules of capitalization are not followed.

Among some groups of people it has been common to include self-classification codes, though the practice is waning.
