No I do not think 862 fans are enough to make anything happen, but that's just the current number joined up since the website opened a little under four months ago. Personally I think having that many within that period of time for a show that hasn't been on the air for over 6yrs (and then some for other countries) is quite amazing.
The more the word of this spreads the more people join up, it's now just a matter of time before we reach and surpass 1,000 and eventually 2,000 and so on. I wouldn't be surprised that if everything goes well (in terms of advertising and word of mouth/keystroke), that we'd have near 1 million before the end of 2008.
