Hi Colin,

This might help:

Maybe it is not exactly what you need, but it help you to get started.

Btw, if you go to the Economy-x-Talk homepage (see below) and click on  
Developers on the left side of the page, you can download a search  
plugin for Firefox, which searches the Revolution mail list archives.

Best regards,

Mark Schonewille
