We'll create fresh WordPress site with Simple Twitter Follow Me Button installed. You have 20 minutes to test the plugin after that site we'll be deleted.
The Simple Twitter Follow Me button allows you to add a small or large Twitter follow button to the end of every post so you can grow your Twitter following with your blog readers and let your audience easily share your content on social networks.
Once installed and activated, go to Settings -> Reading and scroll down to the Simple Twitter Follow Button settings.
Here you can enter your Twitter username and choose whether the button should be small or large.
