Is that functionality actually there? I didn’t see it as an option. I’m trying to figure out what forum/forum software has “Thread OP” highlighted.
It is the setting below. Watch (or set a trigger) on the content (thread) you created
From the XenForo
Preferences screen, the setting you’re looking for is under
Content options.
Correct setting:
- “Automatically watch content you create…”
When this option is enabled:
- Any thread you create is automatically “watched”
- You will receive alerts/notifications when someone replies
- If you also tick:
- “and receive email notifications”
→ you’ll get email alerts as well
How it works:
- XenForo uses a “watched threads” system
- Creating a thread + enabling that option = automatic subscription
- Replies → trigger alerts (and optionally emails)
If you’re not getting notifications
Also double-check:
- Go to Alerts (left menu) → ensure thread reply alerts are enabled
- Make sure you didn’t manually unwatch the thread
Quick summary

Enable:
Automatically watch content you create…
✔ This is the exact setting that controls reply notifications for your own threads.
