Thank you for the answer Loyce. I know such a request will hardly be accepted. I have to try to learn something more to do it automatically. With such thing like neutral, and some others, I can easily edit it.
The real problem is username (with space) and the order of the 'username' variable despite of I don't need usernames. It will be better for me (with my current skills) if it displays at the end. As being said, it is weird to display your update this way.
I think there are ways to do it automatically, it is just I have not yet known how to do this.
Anyway, with some manual works, I get an overview on 504 DT2 members.
In medians, DT2 members received
+2 positive feedbacks,
-0 negative feedback, earned 104 merits.
Maximum for positive feedback, negative feedback, and earned merits are 79, 9, and 5180, respectively.
