I am looking for a plugin for my wordpress website that will sit on the footer. What I want is the type of footer that enables social networking, that will let you share stuff.

An example site: www.duncsweb.com

If you could let me know of a website with a similar plugin, please let me know. I have looked on the wordpress.org site but haven’t found anything. Maybe I’m not searching the right criteria? Any suggestions are appreciated.
