Hi Stuart, TAG, SWEO,

we removed the sentence indicated, see below.

It was Stuart Williams who said at the right time 25.03.2008 15:02 the 
following words:

thanks for the positive feedback - this helps much to measure the 
quality of the current version and defend it against other people 
wanting possible changes.

I think that dropping the sentence is not essential, because it should 
be clear from the other explanations how conneg works and the sentence 
says "indirectly". But - cutting a sentence is always good, keep it 
simple... so I remove it.
