The search engine thing was set up by One More Round, so it might be something that they quietly phased out after ownership of that company changed hands. I'll let Matt know that the link doesn't work anymore and he will either contact the OMR people or we'll just take it down.
EDIT: Matt told me to go ahead and take it down - I guess the program is ended. You might still see the banner on the website for up to 24 hours. For whatever reason, when I edit that particular "sidebar" file, it usually takes several hours for the change to propagate through.
Oh, and BTW, welcome to the forums, Molly!
