That's the way it has ended up so far, I can remember a Football web site I was on years ago, it started up ok with quite a few members then Wums, Trolls etc gradually crept in and the Webmaster did not keep control of it and the web site went down the drain and closed up.
The few remainder members except me then started their own version with only about 6 active members and from what I heard it's still going strong 5 years later but with only around 6 of the old regular members, they all have a chit-chat together.
