Ability to register/identify/ghost our lingering nickname?

[mysterypaint]

I'm not sure how the script actually works, but I suspect that my old username is lingering on the default server for the co-op play, and now I can't use my original nickname. Can we get this feature added in case our names end up lingering on the server?

a /nickserv identify password option would be really good, and i've thought about that… what's a little harder is the ghost logic because I think it would have to pick an alternate nick etc and there are just several steps to this. i'll think about this
