This plugin acts as a quick front-end posting tool, allowing your visitors to easily submit posts and images from the front-end of your site, via a sidebar widget form, or a custom shortcode in a page or post of your choice. 
This is a very easy way to get your visitors to engage on your website. The idea came from a client who wanted a way to let members of their congregation post articles in the main church’s website
