So is it best to totally ignore Aussie French cars, or join up (but not actually participate) and thus prevent misuse of "our" familiar user names.
It is better NOT to join.
Every added member, whether legitimate or not, adds to their site traffic, as does posting their link in here.
What a crazy thing to do, especially if you don't want a rival of any sort to get the better of you. (I realise the person who posted the link is not the owner of aussiefrogs, and possibly has no real interest in seeing aussiefrogs resurrected.)
Cheers ;-)
