In the main title for the ninth season, a piece of paper flashes across the screen listing "FBI Contacts: Witnesses and Contributors." The names on the list are screen names of the series' on-line fans. For episodes #9.01-#9.11, the names were randomly picked from various X-Files message boards. For episodes #9.12-#9.19, the names came from contest entries.
