Sort Q&A replies chronological

Hi all,

We would like to implement the Q&A forum setting on some of our community's subforums. However, the replies are by default sorted by reputation/votes. We would like to have them sorted chronological by default. Any ideas on how to achieve this?

I'm aware that the option is already available in the sorting menu. But we're really looking for a way to change the standard setting.

Thanks in advance!
