Anyone who can view a thread can add an emoji reaction to the thread, or any response on that thread, by clicking the smiley face icon. Your name may appear when someone hovers over the reaction.
You'll be able to see reactions to your threads and responses in notifications.
To add an emoji reaction to a thread or response:
- Go to the thread or response
- Click the smiley face icon
- Find and select the emoji you want to react with
If you accidentally react to something, you can always click the emoji again to remove yourself from it.
