Identify the guidelines to include the writer's identification in a business letter.
1) If the writer's name and title are keyed on the same line, do not separate them with a comma.
2) Type the writer's name in all-capital letters below the salutation, leaving one blank line above and below.
3) If the writer's name and title are keyed on two separate lines, do not separate them with a comma.
4) Type the writer's name on the fourth line below the complimentary closing or the company name, whichever is last.
