ProSocial

ProSocial is a free WordPress plugin which connects your readers with your authors.

It shows an attractive pop-up bar next to your authors’ names, with links to their social media accounts.

On multi-author blogs, it’s a great way of encouraging your readers to connect with your authors on other social networks.

Features:

• 40+ social networks: You choose which networks to display. Your authors can add then their accounts themselves.
• Includes email: Show your authors’ email addresses as well (with a captcha form to prevent spam).
• Google Analytics: If you use Google Analytics, you can see who’s clicking on what.
