because the lack of the CAPABILITIES is enough to tell them that it is not a
mode switching server...

  if CAPABILITIES then {
    if MODE-READER then {
      MODE READER
    }
  else
    // not a mode switching server
    // use standard article retrieval commands
  }

plus they could simply look at HELP and see if CAPABILITIES exists instead of
issuing a command that could fail...

 RC> thunderturkey doesn't issue that command before issuing MODE READER

interesting... i've never looked but t-bird is one of the news readers i use to
 test my news server with...

seems that more than one news reader has it wrong, then... or maybe t-bird has
it right and the others are wrong for terminating...

the RFC can't be wrong... the RFC is what the rules are... software has to
comply with the RFCs it supports...
