If you're having trouble finding the button for registering a NEW User ID, it's because I didn't make the link path obvious enough. There's a "Log In" button in the "Goto" bar just above the message window... and on the Log-In screen there's a link for registering a new User ID and password...
Or you can simply click here: http://forum.britishv8.org/register.php?11
