If so, you can track all things biodiesel with my online keyword tracking tool cellalert.net if you're interested in knowing everytime something related to biodiesel pops up on any site worldwide that you want to monitor. I can show you how to use it (it's still in beta testing) but I can send you a beta test invitation if you would like. Email me for more directions at israel at freealert dot org Or just go to www.cellalert.net and test it out.
