I am looking to add plugins to my blog but there is no where in my dashboard that allows me to even find the plugin section. I have watched countless tutorials and every one of them has a plugin section under the user section in the dashboard. Mine does not and I don't know what to do. Also, I want the categories to show up on my home page in the sidebar and I don't know how to do this...I'm guessing there is a plugin.
The blog I need help with is adperspective.com.
