Hi,
thanks for sharing your challenge here with us!
@Suvi Lehtovaara I think this will not help as this will only send the notification to the user, and not to the community manager. Of course you could simply check your private messages and see if you congratulated a user for becoming a hero, however that message might “drown” between other private messages in your inbox.
Currently, we do not have a notification set up that informs you when a user reaches a certain rank. What you could do however, is to check in the user dashboard for rank changes and the amount of users who own a hero rank.
I do see the value of having notifications attached to certain ranks, so I will take this feedback with and inform our product team. Hopefully we can offer something like this in the future!
