Threads & Replies Why threads Keep channels tidy by moving side conversations into threads. Threads reduce notification noise for people not following the topic. Start and follow a thread Hover a message → Reply in thread. The composer switches to the thread; send your reply. Click “Follow” to receive thread‑only notifications without muting the room. Best practices Use threads for questions, decisions, and sub‑topics. Summarize outcomes back in the main channel to close the loop.
