I want to add a facebook like button and a tweet button, and even google +1 button at the end of every post. At the very least I want a facebook like button. I looked online and found a bunch of plugins but they all say to edit different .php files in my themes folder. I am using the Greyzed theme from the selection WordPress provides and I have no idea how to edit any of it. How can I add the buttons to end of each blog post?
The blog I need help with is twofourfootball.com.
