I've been googling a guide on how to install a plugin on my homepage. I found this: http://codex.wordpress.org/File:plugins.png
According to the picture I should have a menu under "appearance" called plugin. I don't have that. Is this because of my theme (Coraline)? Or?
Any hints or tips would be great as Im making this for my work!
The blog I need help with is skphan.wordpress.com.
