  40 This counter makes it easy for somebody to guess the next nick simply by
  41 looking at nick changes.. It's better to have an algorithm that combines
  42 timestamp with a counter.. e.g.
  43
  44 in nickserv.c declare:
  45 static int guestnum;                    /* Current guest number */
  46
  47 in ns_init():
  48         guestnum = time(NULL);
  49         while (guestnum&gt;9999999) guestnum -= 10000000;
  50
  51 in collide():
  52    snprintf(guestnick, sizeof(guestnick), &quot;%s%ld%d%ld&quot;, NSGuestNickPrefix,
  53             tv.tv_usec / 10000, guestnum++, tv.tv_sec % (60*60*24));
  54
  55   _ _ _|_ o._ o _
  56  _)(_) |_ ||  |_&gt;
