there is a easier way, open the search player function and enter a single letter as the first name (Example "A") this will give you a list of everyone on the server who's characters name begins with that letter also it will give you info on their FC's, after getting a list of FC you can even go to the lodestone and search FC's based on their tags and get the name of the FC. You can do all of this while afking next to Nuffy Chan in MD
Im sure you put alot of work into it, but I know there are some FC's that are not listed, the only one off the top of my head is <N-V> this might be a great tool for people that are looking to join a FC but would rather have a smaller/larger sized member base to join.
Thanks alot!
