If I want to add say google + to my blog it gives me instructions of how to copy and paste the code into my header for example. Within my simple blog where can you change code? I don't have editor, plugins, or anything. I see how I can upgrade to a professional site, but is there no way to go behind the scenes and change things like I did with my old blogspot.com in <change design>...<html> for example.
The blog I need help with is blacklongboards.wordpress.com.
