My guild is never online anymore.

[The Skirata Clan]

My suggestion is to really think things through. If you want a guild that has more activity there are a lot that still have. Find one that suits your gaming style and move on. However if you don't want to leave your guild ask one of those members that still pop up "What's going on?"
You don't need to leave your guild to do the Pearl Recovery or to have fun in game. There are many of us bored and happy to help pirates in here that will jump at the first chance to do a the Pearl quest. You can set up a meeting place and there will be a good number of pirates ready to help. Meet them, crew them, and if you like friend them. That way you'll know other members of this forums, have fun, without leaving your guild.
