WordPress: Delete all comments easily

When you open your WordPress file for your web site you find many comments have been added to the Comments section of the Dashboard.  In some cases there could be hundreds if not thousands.  How do we get rid of all at once?

Open your WordPress program.  Click on Plugins, then Add New.  In the Search bar, upper right corner, type in Delete All Comments Easily.  Hit Enter and the plugin will appear.  Click Install and then Activate.  After it is installed, click on Tools and then select the plugin you just installed.  The plugin will show you the number of comments that exist, you can either back out or click to remove them all with a check mark.

Done.
