Hi Oily and thanks for posting in here. Good to hear that you'll be offering these kits. I think there may be some others out there already doing this as well, but the more the merrier.
Don't worry about sounding commmercial. I have no problem with people making money from biodiesel. While I'm never asking for any money from this site, I've got no objection to helping people use it to promote biodiesel, so please feel free to post up info on it in here. You can also use this forum if you want for supporting and helping your users out with using your home bio kit.
You might get a thriving community in here who are all using your kits. The knowledge shared here would then not only benefit you and your users, but everyone else as well.
I'd also be happy to post an article/some info on your kits on my
sydneybiodiesel site as well if you wanted, so if you want to put anything up, either here or there, just let me know.
Cheers,
