Personas tutorial needs to be updated in time for Firefox 6. Assigning to myself for rewrite/move part, will reassign when it's time to change GetPersonas website.
Make sure tutorial includes screenshots of all platforms (Win XP, Vista, 7; Mac OS X; Linux (Ubuntu?); Mobile).
getpersonas.com has been retired. More information at https://blog.mozilla.org/addons/2013/04/11/background-themes-have-moved-to-amo/
