Welcome back! Did you bring some meatballs for us?
Depending on how long you've been gone, you may or may not find yourself in need of some new friends/a new guild to hang out in the Caribbean with. If that isn't the case, then have fun meeting up with your old friends - if not, however, I would suggest looking around the Crews and Mateys section of the forums here to see if you can meet up with a few of the pirates around these waters to make some new friends.
If you are looking for a more long term group of friends, then I suggest looking around the Guilds and Clans Section to look for a guild that may suit you. Along with checking some of the subforums, be sure to check all of the guilds that have threads here to see if they might be the guild for you. If you think you've found the right guild after reading all of their rules and such, then PM the Guildmaster of that guild, and they'll be with you shortly.
Happy pirating!
