Haha!
I have one suggestion.
It's not really a rule but more of a guideline.
When someone comes online, everyone should say Hello, Hi, Ahoy or just some sort of greeting.
It would make the guild a lot friendlier and "polite".
Often when I sign in only about the half of the people say Hi.
It's much funner to have warm welcomes when you come online

And when new people come to the guild and sign in and get no greetings? That's mot really a guild you would like to stay in?
+Make new people join conversations. It's a BIG + when new pirates are in the conversation.
Just say'in it.
