Thanx a lot, Thierry, you've helped me a lot...

Is there a communication channel (other than this list, given that the
samba-docs list is long gone) for commenting on the documentation itself?

I don't think my stumbling abouts are only because of my particular kind of
foolishness and maybe a couple more notes at the bottom of
help other people (those with my /general/ kind of foolishness :-P ).

Regards and thanx again
