Few days ago I was helping a user solve his problem, the discussion became long in the comment section. I wanted to move it to chat, but I've never ever used chat on SE before and he's from a different timezone so we can't chat. I comment, he replies after 12h or so.
I'm not going to give him my email, nor ask him for his email. So if I leave him instructions in the chat room, will he be able to read them whenever he clicks on the link? Maybe after 2 days or so? And is it private? Like private messaging on forums?
