I was not suggesting that mold never causes serious illness, only that clouds of spores can really give you an allergy attack even if they are the type that don't cause serious illness. This is probably much more likely to happen and I thought it was worth mentioning.
Thankfully John, the bottom of the compost bin is open directly onto the ground, so the worms have somewhere else to go. I knew that system would be advantageous one day!
Haven't checked the pile today, it's been too hot weather wise, now it's pouring rain... that's Sydney for you. I'll check it tomorrow.
