The credits section of the in-game manual lists:

"Richard Fowler for maitaining the FAQ for ADOM. Direct all questions to [email address redacted]"

Given that he hasn't maintained the FAQ for over a decade at this point, it would probably be best to remove the email address.

Likewise, Daniel Quaroni's email address is also listed, as the maintainer for the ADOM spoiler files, and should probably also be removed.
