Hi! It sounds like I need to join a group on a certain giant social media site. Our cruise is a surprise and we haven't told our children or friends yet. I'm always leery about the privacy over there - you can see who's in the group without joining, so i imagine it's searchable. Will it list on my page or my profile or whatnot that I'm a member of that certain group?? Aren't there any fish extender groups or anything planned HERE??
