This very discussion is a good example. Here's why it helps both sides.
I received the announcement about the discontinuation of the Extension Library program.
I was unsure of a few details and so I clicked reply and spent several minutes outlining what I was needing to know.
But I did not get any response except the followup that was sent to everyone. And it did not answer a couple of my biggest questions. So I asked again. Still no response.
But then, I found this thread by accident. As soon as I read it, all my questions were answered, and I suddenly felt better informed. Others had the same questions. I would call that productive. Wouldn't you?
