Social Networking Links

OK, this is a really dumb newbie question. Is it the particular skin on the AA Forum, or is there a mod for the social networking links at the bottom of each post? -->

 

I'm pretty sure you can do this by ending the postbit template, but I'm not sure exactly what was edited.

 

The ones here are added via vbSEO. However there are addons at vBulletin.org that adds it as well. Of course vBulletin has social bookmarking for each thread by default without an addon. Layout of the links could use some sprucing up but that isn't difficult to do.
