Hey Alan!   
      
   I thought I'd switch back to myself for replies and leave the "Little Mikey"   
   ones for testing if and when needed.  I think I've confused myself enough for   
   awhile and I don't seem to be gaining any insight.   
      
    AI> it defaults to type 2+ (4D address support)   
      
   Understood.  I believe it was around the turn of the century when I noticed   
   they were becoming the majority and a few years later that the standardized   
   pktheader was becoming unsupported by the majority of nodes.  Not sure if the   
   sysops of those nodes were actually aware of the change in many cases.  If the   
   only reason for the change was to support 4D addressing it appears not to have   
   worked as far as creating additional usage of fidonet echomail.  I played   
   around with it for a number of years and wasn't all that fond of it, other   
   than it beat offline messaging especially the QWK format.   
      
   Anyhow I am done testing for now and am not convinced I achieved anything in   
   the process.  I am starting to think it might have been better to let sleeping   
   dogs lie.  Oh well ... live and learn eh?   
      
   Life is good,   
   Maurice   
      
   ... Don't cry for me I have vi.
