I'm chatting with a few coworkers on slack and would like to add another coworker to the chat.
The problem is that when I add a new coworker to the group chat, a new group chat is created without the history.
Is there a way to add a person to a group chat including the chat's history?
Threaded messaging comes to Slack
... Say someone posts a message in Slack that you want to follow up on, but the deeper conversation doesn’t apply to everyone. Now, you can kick off a detailed discussion on that particular topic by hovering over the message and clicking Start a thread. The right sidebar in Slack will open, and you can add your reply.
"Threads" are rolling out "in the next few days". More details at SlackHQ.
You can put a comment on any cell, and other people can reply your comment. After the discussion is over, you can resolve it so it get archived.
On the top right hand corner, there is a "Comments" button. You can use it to browse both active and resolved comments. You can also delete discussion threads you no longer want to keep.
