Casuals/socials are free to join long as your nice and friendly, application process only applies to raiders, whisper any of the leaders/officers/raiders they can send u an invite (use FFXIV armory to find out names or names mentioned in the recruit post). =D

Edit: just read your post again, if you are interested in raiding, please do use our FC website to apply for a raid spot. That being said, we are currently quite satisfied with the group we have, but we are always on the look for exceptional players.
