Hi Anna / Moderator,
As per the below post, marking answers, can help identify great solutions and top contributors. But, the 'mark as answer' can only be marked by threads started by user.
Most of the questions posted by the user are just read by user and they might not always "mark" the answer, which will not be helpful if a new user is going through posts with 30+ replies in it. I hope this can be changed by making 'Mark answer' public to all. And consider the reply as an answer if it has a higher 'mark as answer' selected by other community users ?
Thanks for the excellent suggestion. We're looking into ways of improving this feature, and will definitely be taking this feedback into account.
Have a wonderful day!
