Hi Dillyman,
Quite a few Queenslanders are now appearing in the forum. Some are near each other and some are not. It will only be a matter of time before more biodiesel folk pop in here that are geographically close to you. Also, now that you have mentioned your location (I've added it to your profile), search engines will find you here. It takes about 3-4 days now for google to list new posts, so if anyone does a search on "hervey bay biodiesel" they will find you.
I'll also be adding skype integration into the forum soon, so you can have a little icon at the top of your posts and people can just click it to skype you. Hopefully others will find this useful too.
Good luck with the biodiesel production, I'm sure you'll find some help in here. Let us know how it goes.
