Q. What plugins have you deployed and why? How have you deployed and configured them with discussed examples and screenshots?
Akismet Anti-Spam: Used by millions, Akismet is quite possibly the best way in the world to protect your blog from spam. Your site is fully configured and being protected, even while you sleep.
I have installed the free version of Akismet which is a plugin which prevents robots from commenting on your blog posts. By stopping spam comments the plugin allows you to focus your energy on moderating comments made by real users.
