We'll create fresh WordPress site with Date Published Shortcode installed. You have 20 minutes to test the plugin after that site we'll be deleted.
The short description really says it all. No bullshit, no complex stuff, just a simple shortcode that you can copy and paste to save a few seconds. I really made this so that I wouldn’t have to glance at the date every time that I posted an article; quite lazy, I know, but automating stuff is cool, and now I at least know how to put up a plugin on the WordPress repository.
