Adding new flags is pretty easy, but those who are not sure will
most likely find this snippet useful. This will explain how to
add a !CLASS flag to your rooms, making warriors/clerics etc..
unable to enter. A small code is also required. Hope you like it.
-----------------------------[ Step One ]-----------------------------
> in act.movement.c
> in do_simple_move(
> search for "send_to_char("You aren't godly enough t"
> add this under }

  if (GET_LEVEL(ch) < LVL_IMMORT) {
  /* So classes cant enter noclass rooms */
  if (ROOM_FLAGGED(EXIT(ch, dir)->to_room, ROOM_NOTHIEF) &&
	IS_THIEF(ch)) {
    send_to_char("Thieves not allowed, go away!\r\n", ch);
    return (0);
  } 
  if (ROOM_FLAGGED(EXIT(ch, dir)->to_room, ROOM_NOMAGICUSER) &&
	IS_MAGIC_USER(ch)) {
    send_to_char("Mages not allowed, go away!\r\n", ch);
    return (0);
  } 
  if (ROOM_FLAGGED(EXIT(ch, dir)->to_room, ROOM_NOWARRIOR) &&
	IS_WARRIOR(ch)) {
    send_to_char("Warriors not allowed, go away!\r\n", ch);
    return (0);
  } 
  if (ROOM_FLAGGED(EXIT(ch, dir)->to_room, ROOM_NOCLERIC) &&
	IS_CLERIC(ch)) {
    send_to_char("Clerics not allowed, go away!\r\n", ch);
    return (0);
  } 
 }
-----------------------------[ Step Two ]-----------------------------
> in constants.c
> in /* ROOM_x */
> search for "*",
> add under "*",

  "NOMAGICUSER",
  "NOCLERIC",
  "NOTHIEF",
  "NOWARRIOR",
----------------------------[ Step Three ]----------------------------
> in structs.h
> in /* Room flags:
> search for "#define ROOM_BFS_MARK"
> add under #define ROOM_BFS_MARK
> change XX to the numbers that fit your list

#define ROOM_NOMAGICUSER        (1 << XX)
#define ROOM_NOCLERIC           (1 << XX)
#define ROOM_NOTHIEF            (1 << XX)
#define ROOM_NOWARRIOR          (1 << XX)
-----------------------------[ Step Four ]----------------------------
> if you use OLC
> in oasis.h
> search for "#define NUM_ROOM_FLAGS"

Add 4 to the number :P
It sets how many roomflags redit should look for.
