As a heads-up to some people (paid and premium), because that just happened to me: if some strange stuff suddenly appears in your header, that's a new S2 module that was not meant to be displayed in the header - ou can deactivate it or put it into the sidebar here: http://www.dreamwidth.org/customize/options?group=modules

(Seems to be style-dependent where it shows up - I notice that the one on D's journal behaved itself)
