Hey Christoph,
Yeah, that gets a few every now and then.  We've been doing the
append thing for so long, I take it for granted that everyone knows.

I've updated all the man pages to use the word 'append'.

Are things looking better?  I'm hoping the numbers are doing the right
thing?  The bug you reported was a very interesting one, where only
certain conditions could tickle it.  Interesting that your network  
tickled
it more than others.  Very glad you found and reported it!!!!!!!

Thanks for all the help!!!!!

Carter
