I'm having some difficulties with following facebook_tutorial on http://apps.facebook.com/facebooker_tutorial/ and wonder if this plugin is still up to date with the current Facebook API? For example, I'm trying to send notification or post in news feed but get errors like 'Undefined method' however I do everything just like in tutorial.
And what are the differences between Facebooker and Facebooker2? Is facebooker2 written by the same author? I found only simple readme and no tutors at all.
