I can read your mind. You're thinking, "Gee, I would probably make a pretty good discussion leader, but I'm not sure I'm going to have enough time to post regularly in this book discussion forum. I'm probably good for an occasional post, but little more, so I better keep my mouth shut and not take the helm in this discussion."
Oh, nonsense I say. What ever gave you the impression that this job was so serious? Do I look serious?
An occasional post is enough. Just do your best and you'll be fine in my book. And we're a week into March so we do need a discussion leader soon. Otherwise, all sorts of bad things will happen. And you don't want that. Do you?
