I agree with all the comments, its a real shame but Bigpower isn't the only forum to suffer this. Put simply there isn't the people out there with the disposable income they could justify spending on car related bits that there was 3-4 years ago. We like other forums used to have multiple build threads where spending thousands was commonplace. Now apart from a few hardy people this doesn't happen which is a sad.
Also yep as Ben says its hard going through the agro of organising an event where 20 people say yes but when it comes to getting the money this halves.
I think instead of focussing on the track side of things like track days and auto tests, we should also look to more social kind of activities like drives out to places, the go karting or even other stuff like paint balling and things to help get the forum back to the friendly social banter place it was. Also people can bring partners, girlfriends, kids etc to some of these events which too seems to be a big reason why people can't go to things
Myself I wouldn't mind going to Beaulieu or Brooklands or the Goodwood Classic event, an idea may be to drive down and stay the night- have some food and then go to the place the next day and drive back.
But then I was never 'track focussed' and used to just enjoy the friendly socials and watching the track events more.
