I think I commented in the initial post,

We have just turned warnings (yellow flags) to a special 0 point infraction with a Greeting message and green colored.

Launched from user profile doesn't quote report into message and gives thanking PM to user. Another goody is that this greeting it also kept stored in reporter's profile.

Concretely in out forum, autothreads of both infraction/greetings are public acces (but not replyable).

That green card is what we call feedback, and it only requires one click from post report.

Actions taken for the reported post are detailed (Abreviated) in thread title for inform user and better coordination of staff
