   Hey August!   
      
    AA> For msgid purposes why not just generate a 6 to 9 character hash

   The method I am thinking should never repeat and should be good up to -={   
   2147485547-12-31 23:59:59.999999999+00:00 }=-.  That is over 2 billion years   
   from now.   
      
   Currently I am just using the hex representation of an unsigned 32-bit   
   unixtime but there is just me and I can't produce more then one MSG within   
   minutes, nevermind seconds and the serial number generated is unique up to -={   
   2106-02-07 06:28:15+00:00 }=-.  Thus the largest unique serial number possible   
   is ffffffff.  For signed 32-bit integers -={ 2038-01-19 03:14:07+00:00 }=- is   
   the end of the line and will produce a MSGID serial number of 7fffffff which   
   is the largest hex value for signed 32-bit integers.   
      
   If I am not mistaken -={ 2106-02-07 06:28:15+00:00 }=- is the upper limit for   
   Synchronet systems or at least that is what I was told.  When I pay attention   
   to it I have noticed the serial numbers look very familiar to me.   
      
   Your serial number for the MSG I am replying to yields -={ 2097-03-19   
   18:09:50+00:00 }=- which is obviously not a time based generated serial number   
   and definetly not a 32-bit signed integer.

   Since the beginning, which for me was back in the late 1980's on VAX/VMS.    
   Solaris was the first GUI I ever ran across sometime around 1989-ish if I am   
   remembering correctly.  For VAX/VMS Fortran (F77) was the compiler of choice   
   while for Solaris it was C all the way which has taken me up to and including   
   today as I upgrade to gcc-10.3.0 as we speak.  :-)

   I hear you.  I am getting too old for that sort of thing.  Mind you I have no   
   windows that high up.  All mine I can reach without a ladder.
