The decomposing material doesn't technically become a "brown" or carbon. I suspect that the pile simply had enough carbon to handle your additions. But be aware that compost ingredients should be heavy on carbon ("browns"), approximately 30:1 carbon to nitrogen. If you keep adding only "greens" (nitrogen), it will get wet, stinky, and slimy. It's probably better to be liberal on "brown"- the worst that happens in that case is it dries faster and takes a little longer to break down.

If you have neighbors close by, err on the side of too much brown rather than green. Neighbors might not like stinky, smelly rotting stuff around.

Thanks Karen! I go to the bin at least once a week and turn it once a week and it isn't slimy nor smelly - yet. I'll continue to watch it though. As I mentioned, we have no shortage of leaves even now so as long as I watch it, if they need to be added I should be able to do the leaves, or if necessary, shredded papers/newspapers.
Thanks again.
