GADGOOKS! that's no tutorial, that's *torture*. After i finally
got caught up on miised sleep, a few hours ago I read-thru and
listened-to (kttsd) the man lame. Then surfed around; then came

Sounds v promising, thanks.
Given the availability of compression these days, it makes me
wonder why telephone conversations still sound so 'tinny'. But
then, that's another matter.
