Until the search function works, a simple Google search will probably give you what you need.
In the Google search bar, simply type:
<keywords> site:vbforums.com
For example, if I wanted to find the Olympics thread I started, I might type something like
Olympics moonman239 site:vbforums.com
or
2012 London Olympics site:vbforums.com
into the search bar.
I'll create a small code snippet to be used in place of the built-in forum search.
