There's a feature in the forum engine / user groups that makes the Today's birthdays listing somewhat lacking. For some users, that's the reason why their nick doesn't get listed there, and if it doesn't, a birthday thread is unfortunately, though understandably, unlikely. Unless you have here another guy who remembers your birthday by heart... Other than that, right in the middle of the summer is the period when I spend the least amount of time here, or anywhere online, and I imagine it might be so for other people as well. It's just poor luck for lelouch in that sense. Could be nobody was simply ever around to notice.
