A few times I've been requested nicely by the OP to make some kind of contact outside the SE world to discuss an answer. [For example][1]: _"I would like to share and discuss my solution with you, can we talk privately (email,chat,msn,fb) ? this little comment space here hurts me rly"_ I've no objection to this kind of requests, but I'd like to restrict them to the SE realm. SE-chat seems a good tool to do that, but proposing it, and arranging a meeting date/time requires a lot of (almost spamming) comments. So: Can someone come up with practical method for doing this?
