Hey, this could be mighty valuable to nonprofits and so on:
A spam filtering service – Junk Email Filter dot com – is offering free front end spam filtering services for nonprofit organizations. I am looking for 50 or so organizations to start with and see how it goes. It is my hope that I can make a difference in the world by offering nonprofits a time saving service so that they can spend their time and effort doing good work. The details can be found at here.
