Nope. But you can use the [Auto Watch] and [Watch Forum]:



- Auto Watch will automatically subscribe to any new discussions in that forum (the same as if you had replied to them).
- Watch Forum will send you an email when a new discussion is created, but no more notifications for that discussion unless you reply to it (or click the [Watch Topic] button in the thread).

Then get a rule to send those emails to a folder that you can then monitor to see when new discussions popup...
