Want to add replies to questions and answers in Q & A

I have been using the Q & A plugin for some time, and it has been a great addition to Virtuabotix.com, but increasingly users need the ability to reply to a question or answer to get more information, or just to say thank you for the hard work our community puts into things.

Adding additional answers is currently the only way to talk back and forth, but from what I can tell Q & A postings are a custom post type that in theory could actually have replies (much like what you see on Stackoverflow).

Anyways I think it would be an amazing addition to an already great plugin, and hope to hear back on your thoughts.
