Cool. BTW, Christoph, any time I try to send you mail it comes back in a week with a non-delivery notice. So far as I can tell, there is no response from either of your e-mail addresses to any attempt to send mail from here. Not sure why, maybe someone has blacklisted us for no obvious reason (don't have a problem with other correspondents). So if you're wondering why you never get any mail from me anymore, that's why. Randy.
