I know this has nothing to do with data recovery, but since I seem to be the first person to have figured this out I though I'd share. Might be good to generate some traffic to the forum. 
So as you see all the posts now have a Google +1 button. Here's how I did it:
1. In the folder /styles/prosilver/template locate the following two files: overall_header.html and viewtopic_body.html
2. After the <head> tag in overall_header.html insert the following code:
3. In the viewtopic_body.html file find the line:
Then immediately following it, add this code:
You can adjust the size attribute to be "small" "tall" "medium"etc. and the annotation to "none" as well.
Hopefully this helps someone to not spend 3 hours figuring it out like I did.
