It actually shows to each player his admin level.
Try this:

pawn Код:

if (strcmp(cmd, "/admins", true) == 0)
  {
     SendClientMessage(playerid, COLOR_YELLOW, "[ ! ] List of online adminstrators");
     for (new i; i < MAX_PLAYERS; i ++)
     {
       if(PlayerInfo[i][pAdmin] >= 1 && PlayerInfo[i][pAdmin] < 4)
       {
        new 
          adminname[MAX_PLAYER_NAME];
        GetPlayerName(i, adminname, MAX_PLAYER_NAME);           
         format(string, sizeof(string), "%s - level: %d", adminname, PlayerInfo[i][pAdmin]);
         SendClientMessage(playerid, COLOR_ADMIN, string);
       }
     }
     return 1;
  }

Also I guess you don't need to check whether players connected since all pInfo vars are cleared when they connect/disconnect.
