Using new Our Profiles you can easily show up logos and links for 23 different profile services where your users can leave feedback. It provides you a shortcode which you can use in your website posts, pages, text widget and other shortcode supported areas. The plugin provides you two different sizes of logos and also a widget.
There are many WordPress widgets available for displaying links to social media profiles but the widget I am discussing here is Social Media Widget and it is the best one, best because it allows you to add almost all social media profile links easily and also you can add custom profile links too. You can choose from tons of icons which comes in 3 sizes or you can add your own icons. Other than social media profile links it offers you to add links to many more services, email, rss and much more.
