Yep, it's the moment we've all been waiting for - Facebook's timeline is to come into effect for all its fan page administators by Friday 30 March 2012 at 11am PST. Don't worry if you're looking at the clock and panicking about finding a decent cover photo, as that's Pacific Standard Time - and UK users have until 7pm GMT.

Some of the new features include a cover photo, friend activity, larger stories, pinned posts, admin panel plus as an activity log.
Just to be 100 per cent sure of the new changes, administrators are urged to check the requirements for the design. Users can do so here.
