I'm not very sure about this but the logical answer is that if you don't know the number of viewers.. it's kinda hard to pick one randomly. If you don't want to save the list, you could make the script connect, keep the number of the users, pick a random number of those, reconnect and get the name of the picked number.
P.S -Is there any part of the webpage mentioning the number of the viewers before the viewers?
