I have a helpful answer to someone's question, but someone else has put the question on hold. Is there a good way for me to communicate my answer to them without breaking SE rules?
For example, one option would be to post my answer in a comment. In this case I would be hoping that the questioner saw my answer before a moderator was able to delete it. This seems like a poor communication dynamic.
SE rules (for example here) suggest that I could "take any discussion to Role-playing Games Chat" which is extremely unhelpful because the person I'm trying to communicate with is probably not in the chatroom.
What I really want is a way to direct message the person who asked the question, but poking around their profile doesn't seem to reveal that as an option.
In this case the question I am looking at is How do I get stoic loners to cohere into a group and care about each other?, and the answer I want to give is "you can't resolve this in-character, you have to talk about it out-of-character" and a link to https://bankuei.wordpress.com/2009/12/19/a-way-out/. But I've had this problem before as well.
