Once a best answer is determined and an Open Question becomes a Resolved Question, participants can comment on and rate the best answer. Commenting and rating allows participants to add to and give their opinions on answers even after the question is resolved.\nSo based on this, I don't think you can reply directly but you can add comments to the answer.

First get an IM provider. Next launch it, sign in, and double click on your buddy/friend/etc. A window should come up. Type your message and click send. If they're online (your friend list should tell you that) they'll get it and respond if they want. If they don't they don't want to talk or didn't get for whatever reason.
