when i saw this thread i thought someone would pull the thumb out of their arse and get SAU SA organised (seeing as we have SAU VIC, NSW, WA and QLD up and running). The guys I've met in SA are an awesome bunch, and they all were keen to get something official going.
There's plenty of wankers with skylines in VIC, and we still run the club. Its inevitable that they'll join up, but when they do its in the club rules that their membership can be revoked if the committee decides that they are out of line.
That said from the posts you've made it seems that this is more about you than actually starting a club to help the guys on SAU Just remember you need to be SAU SA to operate tightly with this forum. Your personal little car club of hand picked members won't cut it. It needs to be open to the public.
Anyways, this is where I butt out of this thread. Good luck.
