Really congrats them through the core of heart. All three are from my choices however there were a fight between @Oliver and @KronoS and in this fight Oliver won.

All three uas a good contribution on SU community with very humble attitude however I know pretty much @Slhck and @Oliver hut still I have not ever any conversation with Daniel. They all are very active on this SE site and its why they have chosen our mod. Hopefully they all will do the job better than before since slhck was doing moderation related activities anyway
