I found a new blog/web page today that appears to be fairly new but may be helpful over time for very new gardeners or people who are trying to get motivated to start a garden.  She has a free on-line course for composting.  I have not done the course as I just found the web site today.  She is offering a $500 free prize to anyone who enters.  Not sure how big her community is so it may be a good opportunity to win, especially if there are few registers!
