Mutiny is always an option....But what about coming up with a better and more original guild name (I really dislike the deliberate missing letters or misspellings too, unless they are puns, and funny ones at that) In most cases though, the pirates were a very democratic lot, with every man (or woman) getting a say(unless they were in battle) so to be honest, for good or ill, you'd have to vote for the next GM if you are trying to stay true to the good ol' pirate spirit of things.
