I've tried going through General Settings and adding my own site name, Tarot By Michael and also the tagline to, Tarot and Oracle Readings by Michael.
Although I save the page, it still shows up as Just another WordPress site when I try to share it with the Facebook Toolbar share button.
It looks like this
Tarot By Michael | Just another WordPress site
Is there a file I can change manually? I'm using the Twenty Eleven 1.2 theme.
