Yes, yes, I know everyone would say: "No name changing, your friends won't recognize you and remove you!" Well, that's the point, if we could change our pirate's name, a notice goes out to all your friends: "______ has changed their name to ______" when they get back on.
There is this exact topic started by cat25529 (I think that's it) furtherdown in the Shipyards regarding name changing. Some are for it for a one-time thing, which I would be happy to do. However, if you can change your name willy-nilly, then it would get annoying if some consistently change names once a week. I'd get tired of the notices.
So, in all. Get the name change feature in for a "one-time only" option.
