Here's a site with information on composting. It's the Pennsylvania Department of Environmental Protection's page.
I'm still learning. I got a bin, free, from a free worshop at Penn State a couple of years ago. It's not an ideal bin, but there is that old saying, "Don't look a gift horse in the mouth." It looks much more appropriate in my plot than on my back porch (which is where it was for at least one year).
I did not, technically, compost this summer since I'm unsure if I'll have the same plot next year. I hope I do. I did compost casually by piling some plant material in the back of my plot. In addition, getting the soil in my plot ready (which is twice the square footage of my previous garden) took a lot of time. (on top of a full-time job and all.) Some of my garden plot neighbors were impressed by how well I managed a plot of the size that they thought required two people.
