You can't. The only kind of "notification" you can enable is the notification on new posts in a specific thread or forum board.
This feature will probably be available in the new forum software that should be releasing in the future. No ETA yet.
All right, then it wasn´t just me being stupid atleast
Thanks for the clarification
I think you can be still see if you click the button link above near to your avatar its look like this "Show new replies to your posts."
So you can see the quoted or any reply from the thread..
I was also looking for notification but there is no option. Show new replies to your post will be a good option for this..
