I think that it would be better to sort postings by the most recent post/reply date. When a reply is made, bump the entire thread to the top. That would show the latest thought on the forum. When interest and replies drop off, the topic will slide down the list automatically.

The current sorting seems to be by the date of the original posting, and replies are difficult to see. This method does not easily show the most recent replies to anyone's post. It is very time consuming and difficult to scroll down through the postings looking for the newest replies since you were here last.

If others prefer the current method, perhaps offer us the option of choosing from both methods when we are on the Listing page.
