Let your sailor know that the links won't open. Maybe you could share those links in a private email to either myself or Paul and maybe we can help with that. Paul has been on a Tiger Cruise and I know he can answer a lot of your questions. We also have a Tiger group you should join.
Be glad to try to help......without knowing a little more it's hard to offer much advice......you may want to contact the Nimitz Ombudsman
you can always contact me in private at firstname.lastname@example.org
