Hey Mark,
Its true, the US club has suffered low sign ups recently. This is something we anticipated with our recent policy changes and the changes taking place at what is essentially the end of the sim racing season.
Having said that, we also anticipate participation making a comeback in the coming weeks. As the weather turns from summer to winter and temperatures drop, simracing season will be getting back into full swing. Rest assured, you are not the only one teetering on the edge of premium, waiting to see sign ups increase. As those like yourself take the plunge, sign ups will increase.
While the US club has always been somewhat smaller than the EU club, we have indeed seen near full grids, however, if you are available, you are free to join EU or AU races as well.
Hope to see you on the track soon!
