I am surprised that the posting order does not follow the last response. For example if the original post is say  7/20 and a response is 8/31 , the posting should be current, as I see in most forums, not what I see here.

This is important, since a newcomer may want his input to be "current" and also it is better for the existing members to continue the dialogue on what may be an interestring topic instead of getting "lost" at the bottom.
