Please read the rest of my replies before getting yourself worked up over whatever it is that you think I am trying to prove. Note that I'm having some trouble with my email client over the last few days, so read all emails (no matter how oddly formatted) which are by either gad@FreeBSD.org or 'drosih@rpi.edu' (even if it doesn't include my first name in it). If you read them all, you'll hopefully realize that I am not trying to force anyone to do any specific thing, and thus I don't have to prove much of anything. -- Garance Alistair Drosehn = drosih@rpi.edu Senior Systems Programmer or gad@FreeBSD.org Rensselaer Polytechnic Institute; Troy, NY; USA
