Anyone can drop out or stop playing PP. Ranks should be maintained either by vote, pirate rank, contribution to the perks, chat activity, or a combination of them. The guild is not just requirement for getting perks, it is a social channel, we meet and talk to other people. The people actually using the guild should be the ones runnig it, not someone that just created the guild to get benefits from it. We had and abscent captain, I took the lead and created a new one. All the active members followed me. But it would have been easier to just boot the captain.
I disagree @Barbozia the ranks should be maintaned, yes it sucks to have an absent captain. But I advise everybody to find an active guild that is build to last, a guild that has a purpose, a goal. That makes the members more committed, so there is less change to fail in any way
You have no idea those crazy insane sanitation engineers (toilet floor cleaners cabin lads) crazy about promotion!
Oh, but I do. I have plenty of them in my guild who love to nag me about it, and bonus: A lot of my cabin boys are lady pirates. They are NOT happy about being called boys.
