When a moderator moves a set of comments to chat for moderator reasons this is displayed as the only comment in their place:
Comments are not for extended discussion; this conversation has been moved to chat.
Which is fine, I have no issue with the text itself. What bothers me is that moved to chat is a link to the chat room.
When you click the link it automatically joins you into the room. If you close the tab it will not automatically remove you from chat if you are in other rooms at the same time.
I think instead of having it take you to
exchange/room/someNumber/discussion-on-question-title it should take you to
exchange/transcript/someNumber/discussion-on-question-title so that you can look at what was said without actually joining the room. There is still a link in the transcript if joining the room is something that seems worthwhile.
