Me and my friends started a group blog in Portuguese where will blog about Physics and Math. We are tempted to go with the Coraline theme but the problem is that it isn't displaying the author's name together with the post as you can see: http://mardedirac.wordpress.com/
Now I know that it is possible to show the author's name in Coraline because of this: http://climbingthemountain.wordpress.com/
So the question is: what am I doing wrong for the author's name not to be displayed with a post in our group blog. Thanks for all the help.
The blog I need help with is climbingthemountain.wordpress.com.
