變更副板主後，讓被卸任的板主拿下權限，新上任板主掛上權限，這個修改請勿盲目抄

  下面的程式碼，您必須有做「線上變更使用者權限」且新增相關函式，可參考itoc精華

  區。

: manage.c : post_changeBM()

static int
post_changeBM(xo)
  XO *xo;
{
  char buf[80], uid[IDLEN + 1], *blist;
  BRD *oldbrd, newbrd;
  ACCT acct;
  int dirty, len;
+ int has_set = 0;

  ......
  ......

  while (1)
  {
    if (!vget(10, 0, "請輸入板主，結束請按 .....", uid, IDLEN + 1, DOECHO))
    {
-      if (dirty != strlen(cuser.userid))    /* 有做修改 */
-        strcpy(newbrd.BM, buf);
+      if ((*uid == '\0' || !strcmp(cuser.userid, uid)) && !has_set)
+        return XO_BODY;

        break;
    }

      strcat(buf, acct.userid);
      buf[BMLEN] = '\0';                /* 避免過長 */

      move(8, 0);
      prints("目前板主為 %s", buf);
      clrtoeol();

+      has_set = 1;

  ......
  ......

  if (memcmp(&newbrd, oldbrd, sizeof(BRD)) && vans(msg_sure_ny) == 'y')
  {
    memcpy(oldbrd, &newbrd, sizeof(BRD));
    rec_put(FN_BRD, &newbrd, sizeof(BRD), currbno, NULL);
  }
+  utmp_BMset(newbrd.BM, currbno);


: cache.c : utmp_BMset()

  新增這支函式，但請勿盲目抄錄下面程式碼，下面程式碼名單檔的路徑請用自己站上的

  名單檔路徑或是檔名，且須做變更。

  int fd, key;
  UTMP *uentp, *uceil;
  BRD *brd;
  char fpath[64];

  brd = bshm->bcache + bno;
  uentp = ushm->uslot;
  uceil = (void *) uentp + ushm->offset;

  if ((brd->readlevel & PERM_SYSOP) || (brd->readlevel & PERM_BOARD))
