Appears to be an official Twitter feed updated by someone in RDM's production office. Excellent. Of particular note:
And also OMG, BADGE LOGO:
Now would probably be a good time to dispense with concerns, even temporarily, and embrace the squee. ;) Go. Follow. Wish them luck!
Oh, and FYI there is also a Facebook page for the show which doesn't feature the same nifty logo and it's unclear if this is also a Tall Ship-operated page, but if Facebook is more your thing.. there ya go. EDIT: Correction! This is the official Facebook page.
