For me the chosen theme for my main nation transfers over to my puppets as well when I log into and out of them on the same computer. (Which I like.)[violet] wrote:New! Set your theme in your nation's "Settings"!
I've added a box to the Settings page so that you can set a particular theme as default for your nation. This will apply the selected theme whenever you're logged in as that nation, even if you visit the home page (i.e. http://www.nationstates.net instead of century.nationstates.net).
