new bool:CanConnect[MAX_PLAYERS];

public OnPlayerRequestClass(playerid,classid)
{
if(!CanConnect[playerid]) return 0;
return 1;
}

public OnPlayerConnect(playerid)
{
   CanConnect[playerid]=false;
   SetTimerEx("CanConnec",10*1000,false,"i",playerid);
}

forward CanConnec(playerid);
public CanConnec(playerid) return CanConnect[playerid]=true;

This would be correct
