Scenario: Several weeks ago, I had an extended discussion with another SO member in a private chat room (a follow-up to a question I asked and they answered). Now, I am trying out some of the techniques we discussed, and I would like to pick up the conversation from where it left off.
What is the best way to contact the user to resume the discussion? As a user, I would expect to be able to continue the chat (but I can't - the room is frozen), or to send a private message to the other user (which the site doesn't support at all).
I suppose I could comment on his answer, but it would seem out of context, since we've gone quite some length from the original answer and its comments. Other suggestions?
