My first Plugin is here.
You can find the plugin in the official WordPress repository under Plugins Manager in Dashboard or here http://wordpress.org/plugins/zen-social-sticky/
The name is Zen Sticky Social.
What does it do ?
Simply sticks a blue square on the bottom of the page which on hover reveals 2 more squares for the major social networking Facebook and Twitter.
In the admin panel you can find the settings tab for the Zen Sticky Social Plugin in which you can set the Facebook username and the twitter username.
I am here to help if you have any issues using the plugin or if the plugin does not work as excepted.
