give bug address

Please don't say on your man page

      Other comments about find(1) and about the findutils package in
      general can be sent to the bug-findutils mailing list. To join
      the list, send email to address@hidden

Do like coreutils and just give the address.
Otherwise you instill doubt as what will happen with messages like
this one I hereby send. Will it just go to /dev/null?
Give the user an address, not a registration / subscription hoop to jump thru.
