@Devmen " nicest and coolest players you've met and talked to?"
I was assuming that it was to thank some people and give credit where credit was due.
Not necessarily "cool" but actions or cosplay that you found cool. Maybe a person decided for no reason to like your like book, or give you a thumbs up, even a shout out at how nice your character was. Maybe they where nice and cool about you failing an urgent quest and helped you out on something. I think being kind to each other and recognizing people is always a good idea.
