I have developed a free wordpress blog as crmzeal wordpress com. I want to change the theme of the website and want to add some plugins as well. But there isn't any option for any of this. This is the menu I see
As far as I am aware the free wordpress.com blog setup does not allow plugin installation. Only preinstalled plugins can be found and may be you could contact their support to check with them if something is already available within your setup

Thanks everyone, everything has been said.
