yea please guys. when an admin joins, just play normally and dont say a freaking word about it ever. say nothing. if say the person suspected is suspected of aimbotting, try to get celerity and flap/leap around the player to see if he/she tracks perfect or not. dont just do circles, change direction and stuff =p
for wallhackers, get silence and try to ambush someone. use thought and react to what the hacker will probably make a mistake with.
as for specs, one person has to spec. thats it. other people if anything should be playing normally and trying to enjoy themselves =p if an admin joins, just join up and play. (s)he will take care of it.
