Time for a new place for people to leave their questions. I don't forget about the older questions, don't worry about that. Some just take some time to answer -- sometimes I have to go learn something myself. I like doing so, but it takes time. Sometimes, fortunately, some readers already know an answer, so you don't have to wait for me. Of course, other times, I do know the answer and can let you know more quickly.
This is also a place for suggestions of topics to cover. Those, too, may take a while. I really do, for instance, want to get hold of the biofilm article that Hank mentioned in the last question place. Not the easiest thing for me to get. But it should happen.
