Hard to participate
When I read your teaching posts, I always find them very thought-provoking and appreciate them greatly. However, I find it hard to submit questions on them that don't sound stupid. And some questions I submit are never answered anyway.
I want to remain a member, so can you clarify what you mean by "mandatory participation". Do I have to ask questions? If not, how else do I participate? It seems a waste of time to merely reply "Very Interesting", or words to that effect.
Please help me out.
