first mods were chosen by libra, 2nd wave was also chosen by libra on merit. 3rd wave (which included me) were reccomended by other mods & approved by libra, same with the 4th wave.
now we are not mods any longer, now libra has a paid staff for moderation, however it's possible that soon he bring back some old mods since alot of people are not happy with the new mods.
I am not a mod,.. to much work.
