How to report players?

Yes, I know. There's a "save replay" option after you finish or exit a game but what do I do after I save the replay?
Am I supposed to submit the replay somewhere? if so where? how?
I don't think z8games or whoever's in charge of crossfire is making it that clear on how to report players... which is why there's so many of them.
Just a side note for whoever's in charge- Implement an IN-GAME reporting system where you simply click report, type the person's username. and Bam. Simple. Reported. Or at least make a more simple, faster, or clearer way.
Like 90% of crossfire's population has no idea how to report properly.
