changing the name of a sign in Puddle?

[Kimberley A. Shaw]

Hello Steve, or whoever can help:
I've been trying to log on as "editor" (which I'm passworded for) and
change "Washington-city" to "Washington DC" (I know there's already one
there, but this one's a variant) ... and it won't let me change that
particular name! Same thing happened with a couple of other signs which I
had named badly. What can I do from here?
:-(
I think I'll stand at a blackboard now & write 100 times that I will not
go creating Puddle signs when tired ...
Best,
Kim from Boston
