I suspected a bug.

I'll turn up the level of tracing next time and see.

Probably not. It looks like a conflict. If a non existent group is 
specified then the previous one should remain in effect thus demon 
ignores it but complains about syntax. The compuserve one is issuing 
480 where the '8' is reserved for private use whereas I think it 
should be accepting it also. It does look like a NOS bug but it should 
still work. Perhaps the compuserve newsserver is not fully compliant?

>Why is NOS sending GROUP twice?

dunno - like you say, looks like a bug.

>Is there a correcting patch?

Nope.

>Perhaps another solution so that I can post thru compuserve?

Email it to the group as comp.sys.atari.st@news.demon.co.uk

>Is there a NOS/nntp guru?

Nope.

>When will the sun shine again?

At sunrise, smog permitting :-)

>What is in the fridge for lunch?

Nowt!
