You've only been here for less than a week. Ignore some of the people that you didn't find helpful. I looked up the post you were talking about and I would just say familiarize yourself with the forum guidelines, easy to do. There are way more helpful people here than there are snarky posters. Lots more.
Give it a chance and I believe you will enjoy the site. There are so many different forums on here with tons of great information that is kept updated.
Otherwise, contact the admins at help@cruisecritic.com
