Since some servers are not regularly upgraded to the latest level (there are servers which are still running at level 1.3c), I have found very often necessary to use the HELP command only to determine the version they are running. This is wasteful in terms of message traffic, but the command is required to avoid sending commands to a server that it cannot support. I think that a 'Help Version' (or somesuch) command would be useful for that purpose; the only thing to do is to stop message sending after the version number has been displayed. J. M. Blasco
