I finally found Spread the Spark, which is great, because I'd like to figure out how to support this great site!
I noticed you have a Google-powered SparkPeople search page. Is it possible to create a OpenSearch plugin for Firefox that benefits SparkPeople? I use Google every day, but I use it from the toolbar in Firefox. I'd love for each search to benefit SP.
There are instructions on how to create an OpenSearch plugin for Firefox here: http://developer.mozilla.org/en/docs/Creating_OpenSearch_plugins_for_Firefox
